Hi everybody. I want to buy vortech kit for my 2003 G 5AT.
I read a lot about vortech on this forum, but i have some problems.
I'm from Russia, I have no proffesionals in my region to install it and to tune it.
I just want to know when i install it itis necessary to tune it for AT?
And should i buy other things for my car???
AND if in the future i will buy exhaust like injen or HKS should i tune it again???

 

its better to put them all on and then tune it at the end.
Good Luck.

 

Is that easy to tune?

 

If you dont have anyone to tune the car. Dont put any other mods but the Vortech. The out of the box tune is safe.

 

the out of the box is really safe bc it's pig rich and the hp/tq is low 300s. Your best bet is to get your ecu reflashed or find a tuner that can tune your car.

 

I would consider the Stillen if you can't get it tuned over there.

 

Stupid question:
I have a CAI and dual cat back exhaust on my G. I'm doing the headers next.
Should I have my car tuned??? Or do people only tune their cars with major mods??
Thank you!

 

dyno tuning is always a good idea b/c you can get the most out of your mods w/ the a/f ratios are off
