okay guys i got a sct tuner the other day that was on a gt but im using it on my v6 i installed it last night and didn't even really know where to begin i went to the custom tune list and intalled "Blower" well needless to say i started up the car and it immediately stalled out on me :nono: so i went back into the custom tune setting and went threw a couple little things like the 91 octane tune n the air to fuel ration and what not but really didn't no what to do. so i was wondering if anyone could help me out on where to turn. It is a 3.8l v6 with a cold air intake and mac dual exhaust here is my list of questions

91:87 tune am i going to see a difference on which one i use
Air/Fuel i put it on 4% but wasn't sure
i adjusted the rev limiter but thats pretty simple
i also dropped the idle to 540
then we get into the fun stuff .....
will adjusting my plug temps are anything do anything also what is the best for an automatic tranny on shift points it asks in MPH
any help would be greatly appreciated and i'm sure other people are having the same questions.

:rock:

The handheld tuner is just a tool for loading custom tunes onto the car. The tunes that are on the tuner are not designed for your car.

You need to contact a company that does custom email tunes for your modifications. American muscle, brenspeed, JDM.....so on. American muscle is partnered with BAMA and I have heard great things.

Contact them and give them a list of your mods and they will right a tune for YOUR CAR and then you can use the sct to load them.

Do not load the tunes that were on your sct, they could possibly damage your car.

id rather go threw american muscle i go threw them for everything else. but outside of the custom tunes i can go in and manually adjust these things without uploading those tunes. but i think it will probably just be easier to have them give me a tune made for my car instead of me fooling around with it

Def get that tuner reprogrammed for your car. It's tuned for the previous owners PCM and mods. You'll need to give them your PCM code so they can write tunes for your car.

okay so no the tuner is not locked i programmed it directly to my car with no problem i also went into custom tunes and made the mistake you guys read about above. You can also manually tune it which i did with a 91 tune turned off my rear o2 and egt's also moved my air/fuel to +4.0 nothing really else messed with so my main question is i have a intake and mac dual exhaust on the car if i send in for the "custom tune" and pay the money will i see a difference in the aggresion of the car/

Yes you will notice a difference, especially with an automatic. You will definitely want a decent tune if your adding a CAI and exhaust. Actually you may not notice much of a difference until you tune it.
