Tuning

Does anyone kno if u need to get another tune after changing pulley size? Going from 3.6 down to 3.2. If I do need a tune is that something that needs to get done right away or will the car still drive?

I assume it has a blower on it? If yes do not drive the car until it’s retuned.


Pick your poison.

Re: Tuning

The car will still drive fine out of boost, but wind it out and you'll probably find the upper end of the MAF transfer table quickly and go lean. Get it tuned again before actually trying out the newfound boost.

Re: Tuning

Ok thanks. I was wondering if it was something I should just do all at once
