I finally!! got on my 2.0 AwD Ats 1500 miles exceeding my break in period so you can say.. even tho it's a lease... I was kind of disappointed how the power tamper off .. (Not sure if I had it in sport mode) I know I read about this in other threads .. Figure I get your guys opinion... I just bought the trifecta tune hoping this helps ..this helps ...

it's a single turbo trade off

small turbo, fast spool, good low end to mid power
bigger turbo, more lag, will hit hard when it spools and keep going till the rev limiter :)

I test drove an AWD ATS and a manual RWD model and I can tell ya the AWD Automatic felt dogged compared to the manual rwd

I can see the AwD being slower but guess that the sacrifice you make for good handling in bad weather ... Which was amazing in my Cts which I hope follow suit for my ats didn't have a chance to try it this year when I make my runs up to Vermont . I was getting on the highway and punch it full pedal to the floor was moving real nice up until about a little over 60 and them it felt like it die out and kick back in at about 90. I miss my cts a little bit lol

i have a 2.0 t with 300 miles and the top end power is really bad mid range is ok sometimes the car feels like something is holding it back. Really not impressed with the performance. JoeyCts
Please let us know how you like the tune. They claim extra 50hp

I have a 2.0 RWD MT. I agree that when you get up in the revs the power cuts off. You really have to shift far before the limiter. Easy enough to do with a manual. Try driving it in "manual" mode to play with the rev range. I have heard that cars learn based on your driving (e.g., shift points, throttle input, etc.). I don't know if this is indeed true, although it is plausible. If true, you can probably teach it to shift earlier in automatic mode with some patience and diligence. When you decide where you like the full throttle shift point, whenever you get on the car hard, let off on the throttle to cause the car to shift at that point. May or may not work. Additionally, if you can teach the car, it may not "learn" any new traits under circumstances like full throttle. It's a thought though, or maybe someone else here knows more than I do on the subject?

yeah it has a redline at 7000RPM but its not necessary, if I'm having some fun or whatever I'll never shift after 5,500 because after that it falls on its face. I dont know why they gave it a 7KRL, it doesnt need it, these aren't Honda's, we get our power when we need it, not at the very end. I think the ATS' power band is brilliant, the torque is with you all the way through till the peak HP shows up.

My ats is automatic ... I wish I had Manual but I have a wife ... But when I floor my car I don't really have choice when it shifts.. I had the pedal to the floor and it def rev above 5500 rpms and def die off ...

anyone with 2.0 t Auto experiance viabration between 40 and 50 the whole car starts to shake it looks like its in 5th gear going in to the 6th i brought it to the dealer yesterday and we were able to reproduce it at first he said thats not normal but after testing it with another car they saying its normal.

That drop-off in power after 5500rpm was very evident during my dyno runs. Both stock and tuned, the graph headed down after reaching this point. It appears that to keep boosting a turbo upgrade will be needed. Pfadt has several upgrades being released in a few weeks that should really help. Stay tuned. :)

Get a tune. Select the Sport mode and you're done. You'll never drive in Touring mode again. I have not had it on a dyno, but the difference is dramatic. Power pulls through 6000 rpms.

I got the email from Bad News Racing with my tune just waiting for the cable .. Ill keep you updated cause I'm a hard critic .. Won't be putting it on a dyno ... ill be judging with good all fashion dropping the pedal to the floor .. Lol

BNR reported that this was also due to a glitch with the tuned vehicles with a manual transmission and supposedly they've fixed that now. So here's hoping it's much better with a proper tune. I'll be loading mine up this afternoon =).

Our Borg Warner EFR turbo upgrade along with the Trifecta tune is the answer....lots of power in these things!

Those guys at bnr are the real deal and they will take care of you. No need to Dyno. Just order the tune. I have.

So I finally loaded my tune on my car ... I had a minor Hiccup installing it ... YOUR CAR MUST be in SERVICE MODE when loading the tune NOT ACCESSORY mode ... ( or what ever it call when the radio stay on) VERY IMPORTANT . If you flash your car in accessory mode only a partial flash will install and your car will not start !! Scared the shit out of me .. I Contact Jerry from BNR ... He ran me threw what I did wrong .. Guys are great a BNR !!.. So my opinion of the tune is amazing ... I really! got on the car!! Changes the whole dynamics of the car no joke ..
You can fell the hp increase in sport mode without a doubt ... My question is in the long run does this put extra STRESS on your engine? It almost doesn't seem right how you can gain so much more power out of the engine .. The tune also slightly change the drive in tour mode ... Car idle louder ...

These engines are build very, very well, I wouldn't worry about it, as long as you're not driving like mad max every second of the commute you know? like I Said before with cobalts, guys with 2.0T's have 350-400HP on stock internals track there cars and have no select-a-tune, so they're always on full power, and those cars have well over 70K miles on them with no real issues, you're fine man :) GM just builds these engines with huge buffer zones, you'll start getting questioning engine integrity when you slap bigger turbo's on and pushing 400-500hp lol, but with just a tune, dont worry about it.

More power more stress! Heat/stress . Just datalog regularly change your oil more frequently. Good synthetic.
As Dino oil degrades under high temps. My question is how long until the cats get blown out the exhaust?

Long run, short run, any run it puts extra stress on the engine and everything downstream from it. Same goes for pressing the go peddal harder with no tune. No way to know for sure how much it shortens the life of components. With any luck nothing will break while you have it and it will just reduce the value of the car when you sell it (unless you lie about the tune). If the tune is a good one, its probably well worth the cost and risk.

But there are bad tunes in the world and people with them often don't find out until its too late, even from very good sources. Several new Mustang owners had to buy new 5.0 engines because more than one industry leading tuner misunderstood a change Ford made in how their maps worked. That misunderstanding eventually resulted in cylinder 8 piston failures and $8k repair bills for the unlucky customers. I don't know about Trifecta/BNR but most tuners do NOT warranty anything that happens as a result of using the tune.

While reviewing tunes is very valuable for others (thanks for yours), it might cause owners a warranty problem down the road. The manufacturers have people monitoring the forums. They do some really great things by helping owners with service or dealer problems. But most assistance requires you to provide identifying information such as VIN, dealer, purchase date, etc.. And when a manufacturer decides a particular behavior is bad for their business, they have been known to use that information against the customer. That has included knowledge of tunes being used. I beleive BNR advertises that the tune can be removed with no sign it had been there. And I think its wrong to hide the use of a tune if it causes a failure but I also have seen manufacturers use knowledge of a tune as a basis to cancel warranties and deny repairs that were not caused by a tune (or other mod). Being able to remove any trace of a tune is pointless if the owner has talked about their tune in a forum where they have ever posted any identifying information.

I agree with H-D. It's a buyer be aware of what your doing, and there is always the chance of voiding your warranty. Having said that, a lot of people will still get a tune because the lure of more power. That's human nature, to want more.

Not my Ats but a friend of mines ... Haha.. Guys don't scare me... I was already skeptical about tuning ... When taking it to the dealer .. When should I flash it back to stock ?? Meaning what services would they do to make them check for a tune .... ( and on a side note we are talking about a lease) Once flash back to stock could they ever tell...? Thanks for feedback you guys been a lot of help ...

Yeah, you got the idea ;) A friend of mine say he's going to remove it anytime he takes it in. Not to hide it but to keep it from getting overwritten or interfering with any updates they decide to do with your car. He heard of cases where a dealer (not Cadillac) wasted time and wasn't happy about it (time is money) because a tune interefered with some diagnostic procedure they were doing.

I am pretty sure if GM wants to see whether the ECU has been tempered with, they can do it. or see how many times its has been overwritten or so forth...

If you tune, they have grounds to void the warranty. It is a risk you take to get more "fun" out of the car. It is like you flashing a custom/jail break firmware to your phone and you accept the risk of bricking it.

The problem has to be a direct result of a tune. They can't just blanket void your warranty. If your AC goes out they can't blame the tune. Now if you blow up your motor then yes, they will blame the tune. So I would not worry too much. As long as the tune is tested and your AFR's are good, you're not over boosting and there is no detonation you will be fine.

So I install my friends car back to stock today just to see the difference .. Cause the way the car was behaving was insane ( insanely fast ) .. so In conclusion it is like your not even driving the same car ... Insanely slower ... With the tune installed the car in sport mode shifts very hard.. I hope I'm not beating a dead horse but it seems just stressful to me on the engine... I did data log and express my concerns so will see what response I get back ...

You can adjust shifts in tranny IE.. SOFTER,HARDER

More boost more power = more stress...
Oil pressure and monitor EGT.
Fluids,data logging change your oil frequently and use synthetic.
I always run 94 less chance of detonation...
