I have a mostly stock 2006 GT. My plan is to put 20" wheels on it in the coming future. I have already put on a BBK Performance Cold-Air Kit that did not require a tune. Which tuner would be best to reset the speedo for the larger wheels? I was also wanting going to tune for 93 octane gas for future engine mods. Also, could a tune be done for the cold-air kit even though one was not required?

 

SCT or Diablo and Yes.

 

Most people prefer the SCT X-Cal 2 and it has very broad support in the performance tuning community.

The vendors of these devices normally will include some custom tunes which are tailored to your setup as part of the purchase price ($379). Do some searches. There is a ton of information out here already.

Anturner can definitely be used to maximize your BBK and adjust for 20" wheels, different gear ratio, etc..

 

Thanks for the info.

 

De nada my friend. Prepare to be impressed by the jump in performance/responsiveness when you go to the tuner .
