Dyno Results

[CadV]

I am going to try to be as civil as possible because I am really pissed off right now. The dyno is 20/20rwhp on the low side so you can add that to what you see.

Low numbers were done with the 2.55 pulley tune:



I wish you could see the air fuel ratio but it was beyond lean. Afterward we reviewed the 2.55 tune to stock and saw very little difference with no added fuel for the increased boost. Granted mistakes happen but they told me it was not a pulley tune.

Next run was after we fixed the tune. As you can see the car runs great up until 5000-5500 where we started getting detonation so he shutdown. So I got around 520hp/tq at the 5000-5500rpm mark before he let off.

The guys helping me with the car used to work for a well known r&d shop so they put in a call to a friend where he said point blank the car does not provide enough fuel and a fuel booster pump is required. This was not some chump they spoke too either it is their head engineer saying this. I am holding off disclosing any names.

I do not recall that information being conveyed to us and that is what I am most angry about. Who has the correct information that is what I would friggin like to know?

I want to say thanks to Pat at Quality Motorsports because he burned a lot of his day helping me with this. His brand new stock V did 450rwhp on a very hot day.

Some side note stuff. Installed a 160 TStat with no changes to the tune and it did not throw any codes. Also flushed radiator and went with distilled water and water wetter and saw a 10 degree drop on temps.

Cadv know your frustration- see previous posts

How did you fix tune- did they use a new tuning program- efilive? HP?

So your tech is saying we need a fuel booster at a certain boost pressure?

[whisler151]

So you were 435 and 423 with both pulleys, 90mm TB, intake and the W4M pulley tune? I was hoping to see your numbers up near 600. I thought the W4M tune was supposed to help your power. Any idea why your A/F ratio was so lean with the W4M tune?

Is your engine alright with the engine being so lean? Detonation doesn't sound good.

The tune was made from scratch using HP Tuners (3 guys with a ton of experience put their heads together to come up with it). Yes he said we need a fuel booster but I am unsure at what level we need it. I am working through the issue with Quality Motorsports and I will keep you guys updated. Basically I have to baby my car right now.

435 was with stock TB, modded stock airbox (another intake mod that Quality is going to release in the future), and w4me tune. We think the tune was a mixup because it did not have the fuel changes you would expect. Basically a mislabeled 2.55 pulley tune but in all honesty I have no idea.

We did not get detonation when it was running lean only after we started giving it the fuel it needed. That was only once and he shut it down.

I remember the A/F ratios were 10.35 and 13.x just not sure which one is when it was running lean. I think it is the 10.35 but I am prolly wrong.

It sounds like you didnt flash in the CEF file correctly in the handheld tuner and or flash in the correct tune. 1.28515625 1.28515625 1.28515625 1.28515625 1.271484375 1.263671875 1.2822265625 1.3154296875 1.4541015625 1.45703125 1.45703125 1.45703125 1.45703125 1.45703125 1.45703125 1.45703125 1.45703125 1.45703125 1.408203125 1.408203125 1.408203125 1.408203125 1.408203125 1.4287109375 1.470703125 1.470703125 1.470703125 1.470703125 1.470703125 1.470703125 1.470703125 1.470703125 1.470703125

are the eq ratios that im asking with is a MASSIVE amount of fuel added compared to stock in the CEF i sent you. If they dont match these values then the CEF file was not loaded that i emailed you. I KNOW the tune works for your exact mods as I have the SAME tune on my car which works perfectly as does with all the other cars i have tuned here in person with the SAME mods. If the tune wasnt working then it was simply that..... The CEF file was not loaded correctly into the handheld.

I have warned EVERY ONE there are no supprises that when you are near your 600hp mark then you are DONE... The car cant safely supply any more fuel to support the extra horsepower... I say it every day.

Your 255 upper and 8% lower is the max you can run.. You should be at the 588-600hp mark to the wheels now. The only reason you wouldn't is your stock airbox. Which ALSO plays with the airfuel ratios..

If your shop wants to send me the Read from what they pulled from the handheld i can check it here and can see what you actually have in your ecm at that time and check. But im VERY sure that if it was the right tune, it should have been dead on.

The 255 only pully tune you originally had of coarse will be lean as it wasnt set up for the 5% pulley also which adds a ton more power. Without the 5% pulley is will show 11.6-11.8 on the af all the way thru the rpms at wot..


The shitty thing is, that if you could have just waited a few hours, i could have talked with you and walked you thru installing the cef file and then your warrenty wouldnt have been void on your engine /transmission now...

CadV,

no worries man! it will get solved. it is just a matter of fine tuning the tune. i do tune all my cars my self and i know how it gets sometimes I know that Jes will help you quick it is not that hard really. if you need my help, i am hear for you

[CadV]

Jess has been real responsive so he suggested I put his 4" intake on which I just got done doing. Updated the tune on my handheld and trying to get a dyno lined up.

Will keep you guys updated.

He did say we shoud not need any fuel mods below the 600hp mark. Jess also said A/F with my mods should be around 11.6 any more than that and the fuel system cannot supply the needed fuel. The last run we were doing 13.x.

CadV,

Sorry I missed you at Quality yesterday...but maybe it was for the best after hearing about your bad day. Let me know the next time you go to Quality and hopefully I can catch up with ya!

Hopefully picking up my V today!

Just got back from round 2 and the results are still not good. Massive amount of gas was thrown at the car (9.x A/F) with Jesse's new tune and it ran crazy rich. Even after leaning it out to 11.5 I never did over 500rwhp. The best I did was 520rwhp with Quality Motorsports tune and we ran into the fuel restriction at 5000rpm.

I have had a bunch of people review the tunes given to me and there have been a lot of red flags.

Lingenfelter was asked about the pulley combo and they said flat out a fuel booster pump is required.

I am not getting into modifying the fuel so I am backing out of the blower pulley and going to stick with a 9" crank ring if my motor and tranny are ok. My car is not running good right now.

When you do anything to your car get a computer on it and dyno it. Don't trust the tunes.

So does this mean the tunes and mods aren't living up to what they claim?

[Luna.]

I'm just baffled as to how low the numbers are, even for 20/20 low. My lame car only needed a tune to get to 520 rwhp. Keep in mind that comparing dyno to dyno is dangerous, but still--that's a HUGE gap.

I'm hoping to get 560-570 with crankpulley, headers and Corsa exhaust. I'm thinking that's pretty reasonable...

[Gary Wells]

Sorry to hear that you are having problems, CadV, and I certainly hope that you get everything straightened out to your satisfaction. I can only imagine how disheartening this is. You might have saved me a lot of money, though, as I am just getting ready to get one of these, and I think that I will go very slow on the mods. I get frustrated even when my '87 turbo Buick isn't running straight up, and I can only imagine how this feels with a pricey ride like these. Good Luck with everything. I am sure that you will get it all together & running top notch.

Cadv-

Are you referring to the WFM tunes most of us are running as having faults?

What specifics are your techs referring to?

Most of us appear to be ok-see no other reports of tune problems
