... picked up 20 RWHP/16 RWTQ with the new F.A.S.T. 90/90 setup and SLP MAF. About what I had expected and it really flattened out my torque curve ... pushed the power curve up more mid to high range right where I was hoping for. I also saw better performance through the entire power band ... over the LS6/ported stock throttle body/stock MAF setup. The intake was not ported, so, I guess that will be my next objective before spraying.
Just got tuned....
I picked up 10rwhp and lost 6 ft. lbs tq.
Definitely was not what I was expecting....but still happy nonetheless cuz I runs better and did not break anything
Not terrible for old 2003 Absolute Speed heads

I'm installing a FAST 78MM and ported TB pretty soon. I'm getting them used for roughly what an LS6/Ported TB costs, so I don't feel bad buying them. I'll be installing a TR224 cam and LTs at the same time, so hopefully I'll get quite a nice gain with them.
That's what I did, so, I hear ya' brother. Good luck with your duno and track times. As I said, it'll be some good gains. I saw about 15/10 with my LS6 intake and ported Jantzer TB. It's def worth the money.
