Again, I really like the v8 version. I've seen spikes in boost from OBDII app (Dashcommand) at 16.2 psi, but this was right at shift. 13-15 psi seems normal on wot. I have actually started babying my car more now, only cause I worry about hurting the drivetrain. If I Drive in D instead of S it seems easier on the car, but S is much more fun. I use this car for a daily driver so I don't want to kill it. Even though I still may upgrade DP's and CAT back.
