Oofah! The people who told you about the 3.2 didn't happen to be an engine shop, were they?

First and foremost, get a scanner to see what your car is doing. An even better investment is the DHP Powrtuner, which not only scans but allows you to change things around as you mod further.

In my case I've got a FWI, 180 tstat, and DP. I'm running a 3.5 and still having KR issues. So whoever told you to go 3.2 with no mods is uh, how shall I put it, WRONG!!!!
