Installed Comp Cams Stage2 VSR, Revs high at Startup
#12
2 Thumpr's and a Brenspeed tune??? I have a 2007 Mustang Shelby GT with a 5spd & have thought the Thumpers. Brenspeed says I will lose off the line however will gain at top end, also that it would not be good for city driving. What has been your experience?
