Jeff,
Mine busts em loose pretty good when it hits 2nd. Anything over half throttle produces a nice bark - WOT makes em scream! Kinda harsh for normal driving though - although I dont think that is the norm. I think my solenoid pack may have trash in it causing the harsh part throttle shifts. Jason has one too, and his is very tame compared to mine.
Check out the vendors section. I got mine from Speed Inc., but Lightning Force Performance may have them too - and LFP is in the Houston Area (sorta).
