ok...some of you have looked at the thread I have about my cars dyno results.....so...i figured id start a thread on tunes......now just like the exhaust one I did....its going to be a poll w/ the pros and cons and why you use what you have...its open to all....even those like me on stock tune....Im not looking for wild or high output tunes being this is my daily driver....cops and I already dont get along....but id like some room to improve for light track days.....some "sprited" driving....but flexable enough to be civil on the street......I know about HP tuners and of course the GMPP kits being Im probaly going stage 2 route....but like I said....its in the research phase.....Ive spent the last couple of days going thru the search on here....it has somewhat enlightened me.....so have at it boys and girls....oh..... and if the vendors would like to chime in....that be a great help....

 

I have an INTENSE tune, people say its not really good though. Hasnt given me many problems. INTENSE reccomends 1 step colder copper core plugs for their tunes, as well as a gap of 0.040"


But hopefully before the summer is over, I'll have a ZZP Tune
I REALLY hope I can take my car to ZZP and have them Dyno and tune it on the spot. Otherwise I'll have to mail my PCM in like I did
to get my INTENSE tune.

Other places could be OTTP (Over The Top Performance)
They are on the oppsite side of the state as ZZP is.
Intense is down near Dayton Ohio, OTTP, is somewhere North of Detroit Michgian, while ZZP is near Grand Rapids Michgian,

I believe all three can email you the tune, and then you can use HP Tuners to upload that tune into your car, and/make adjustments
to it. Also you can mail them your PCM, they can tune it, and mail it back to you.

... also, I could be mistaken but,
From what I understand HP Tuners is just tuning software/hardware more like do it yourself.

 

The tune doesn't get you in trouble with the law, the right foot does

Even cars we've built with 400+whp drive incredibly smooth and nice around town. It's all in how you drive the car! More power doesn't necc mean poor drivability or the inability to drive slow still.

 

I'm gonna get hp tune on my some day and it's sounds like one of the best to run

 

The cop reference wasnt due to law breaking....cops where I live just don't like cars like mine...not cobalts in general....there are a few up here one like mine minus the rims that have been confused with one that's doing something....it's more along the lines of easy to diag or adjust or whatever....my service extension is almost up....so just making sure it won't come back and bite me in the ass...plus since I'm in social....they are somewhat ******** when it comes to emissions and aftermarket products....

 

HP tuners. If done right it will be actually made for your car in your climate, rather than a canned tune for billy bobs car with somewhat similar mods half way across the county.

 

ok....heres a question for the stage 2 people.......are you still using the one in the kit...if not....what are you using...

 

BumP

 

Vince @ trifecta

 

people still use Intense? Damn I remember back when they were grenading L32 Grand Prixs, lol

 

Find some reputable tuner. Near u with hptuners

 

hptuners./thread

 

this^^^... have been using hpt for over a year now. Love it, you can do just about everything you want to your ecu. The hpt forum is also very helpful and informative. Once you learn all the tabs and features it becomes very easy to use.

 

Trifecta modded GM Stage 3. Best operating system for the LSJ, period. Follow it up with a custom HP Tuners tune if you want and you've got a winning combo.

 

.

Any tune with trifecta and/or good hpt tuner is the way to go

 

HPT - because i said so

 

Hptuners.......

 

Ok....I'm guessing hp tuners is used a lil bit....lol....anyone know who does hp tuners in socal?

 

Dude, its socal. I bet you could throw a stone in any direction and hit someone with hptuners.

 

Just Becuz someone owns hptuners don't makem a tuner. But he has a few not alot out there.........

 

Yeah....it's one thing I know well....not saying anything bad about anyone...but this is my daily driver....work...pick up my kids....can't just trust it and hope it comes out ok....also...thanks to all for your input and ideas....

 

You are welcome, im From Visalia btw or how ever you spell it hahaha, and move to northern cali my whole life till now hahah

 

lol.....yeah Ive lived in socal my whole life except for about 7 years (army)....i plan on doing the tune last....still got a few parts to get....mostly exhaust and about 99% sure on the stage 2 kit....and that will proably do it...at least for now...

 

i just tuned a guy that had gmst2 and he had a intake only on it, well after my tune the guy litterally was amazed on my tune, i changed most of the mapping and had about 6 resions to it so about 3 hours but he said it felt alot faster, my main concern were the fuel trims, they were out 16% in some areas and 20+% in some so i took care of that, i have him running a afr of 11.5 and atiming of 25* in most areas and some 26* is others on the top end.. So getting a tune ontop of gmstg2 will make you quicker, just find a reputable tuner out there

 

yeah..thats what Ive been doing fo the last 3 days....right now....mods are typhoon intake only for the engine.....Ive mostly done the easy stuff....springs....slotted rotors/hawk pads...and when my extended service runs out.....then let the fun begin.....
