You're running a small cam and the converter was unlocked. Are you also running a 92 intake/TB setup? Lots of variables with these H/C setups that can make BIG differences.

Yea I guess my cam is small by today's standards! I have the LS6 intake with CAI, but OEM size - 78mm I think?

Maybe the FAST will allow the heads & cam I have to breathe a bit more down the road. What's the typical gain from the FAST?

Thanks!
