Thanks guys!
Moparmk, yes, an ECU tune should add around 20 more whp, according to the tuner guys. Also the tune increases the rev limit (to 6200, I think), and should allow the car to be dyno-ed properly. That should be it for me for a while. My checkbook is already smoking.

I just hope NeedsWings takes his time getting those intake plenums to production...
