: Would 15 horsepower gain from a tune make a difference?

Would I notice anything significant on a stock 2004 CTS-V if I had this done to it? Is it worth the price? Guy said it would give me 15-30 hp. Thanks.

Hands on tuning is far more likely than mail order tunes to achieve the gains you are talking about. (I can't tell which kind you are looking at.) A good tune will give a noticeable power (you will notice 15hp) increase and improve your gas mileage.

It is going to be an in person tune. Is $280 worth it? Based off of what I mentioned is this a good deal and will it make a noticeable diff? Thanks.

$280 is a fair price. I charge $250 for manual cars and $300 for automatics.

Quit contemplating and just do it!

That's a great deal on a tune. For the LNF in the Cobalt SS with direct injection VVT and all that stuff, good custom tunes on HPtuners START at $400 most of the time. One of the many reasons I like the LS world... And in comparison tuning the LS is like operating a coal fired stove while an LNF is like a nuclear submarine.

Damn Brian thats cheap care to come up here and give me a tune? The local guys who are real good charge about 400 for a tune.

Ya no kidding around here they are around 600-1000 for a tune (NJ area)
I wasn't going on that ride though, I drove out to get my tune.

I'm skeptical about anything changing as far as *Transmission Performance* goes, sans the skip shift

Maybe I should start a traveling tune company. Haha

I'm sure you could get a full day booked up here. (Pa) I spent 500 for my tune and I have issues with my idle searching. Took it back once already.

MoJo2001 where are you located?

People get stuck on peak numbers. A good tune is a lot more than that. Driveability, throttle response, more tq/hp in the low to mid range RMP (where you are most of the time). These are the things you'll feel after a good tune.

Do some research on the tuner. Not every tune is a good one.

Also: If you do it, get a copy of your tune and post it on this or other trusted forums for someone with experience to look it over for you. Actually get a copy of your original tune with the new one.

I think part of the reason people get stuck on peak numbers is that, most get tuned on a dyno. Where you gauge a lot on hp numbers as opposed to fuel trims and ve,pe etc etc... I dynod a street tune I had dialed in on my last car and there wasn't anything I wanted to change driveability was great and numbers weren't bad. Power under the curve was phenomenal. Part of making good hp numbers is making it reliably. If you burn a piston from running too lean or knock, then the extra 10 HP from a few more degrees or a leaner tune is worthless.

Anybody in here know any good shops to get a tune at in San Diego? If not, anywhere in Southern California?

Why would you need

Transmission torque management system reduced (*Transmission Performance*)
Transmission shift points enhanced (*Transmission Performance*)
Transmission shift times reduced (*Transmission Performance*)
Transmission shift pressure firmness enhanced (*Transmission Performance*)

I think thats a waste of effort since you have a manual...

Find a local dyno that does Vettes and let them work their magic on your car...

You have the potential of gettin better mileage, as well as more power, but only if done properly

There is Cunningham here in temecula, excellent shop, they do some nasty stuff with vettes, the owner rocks a c6 with enough power to alter the earths rotation. This is probably where I'm gonna go when I want to get engine work done since I don't have a lift and machining equipment and stuff: http://www.cunningham-motorsports.com/

Excelsior in San Diego... My dad's buddy had a car built there. http://www.excelsiormotorsports.com/c5-corvette-supercharger-418-ls2-stroker.html

JR Competition in Escondido. My buddy is having his Saturn Sky redline done there. Turbo swap along with extra injectors and tuning for ethanol. And if you can tune a LNF motor for ethanol you can do a LS engine no problem. From what I have seen they are doing great work. http://www.jrcompetition.com/

Awesome! Thanks. I'm going to have some cash burning a hole in my pocket once I get my tax return so it's time for some upgrades. :)

Who did you use? Once I get the time to install my Kooks, I'm thinking of using Mikey from Rapid Motorsports from Reading, PA who uses County Corvette's dyno (West Chester, PA). Quoted $300 for tune and $150 for dyno time.

Sweet... I owed another $1k this year so no such luck for me. In all honesty if you are the adventurous type, go buy HP tuners or EFI live on your own. Then learn how to tune your own car. There are tons of good guys on HPtuners forums will to help and I'm sure efi live has something similar.

Tune time in jersey. I wish he would have driven it some. Instead it was only on the dyno.

Wow, I just checked out both of those. Sounds very interesting I'm just afraid it may be beyond my knowledge and/or ability. Is this what you do?

I actually just read a few reviews on the Wait4Me tune. I'm actually kinda interested although I'm guessing I'll be better off with one of the shops you mentioned.

I am kinda lagging on my V. But I am waiting to get off my ass and install the wideband sensor I have in my garage. I'm planning/paying for a wedding so time and money are at a premium.

Congrats on that. We still need to link up sometime. I'd like to check out another V and get some opinions on mine. You ever in SD?

Not as often as when I was living in Carlsbad. I keep meaning to go to cars and coffee there but my work schedule dictates that I am busy on weekends. I'm hoping that will change soon so I can get to more meets and track days but only time will tell

I'm guessing we'll meet next Sunday for the Palomar cruise.

For sure. I have to work that afternoon so I probably will go straight home after the cruise and skip the BBQ action.
