supporting mods such as what? the only supporting Mods I had, running 15psi on a T72 (bone stock motor/tranny/rear) was 42lb LS1 injectors.

no alot more then that. The way the M90 would bolt onto the L32 in the f-body, the intake of the blower is pretty much in the firewall and shit…then all the pullys are on the back…its a mess.

WHAT THE FUCK are we all bench racing a v6 camero exhaust system?
Bring it to albany speed. Make a pass on the dyno get a baseline. take 5 minutes and cut the muffler off at the cat and run it again, open dump. Find out for real what it does.
then put on your new exhaust and dyno it again.
I bet it doesnt make more than 3-5whp more.
