To the OP you may want to mention you're running a big cubed motor.
The FAST 90 can actually cost HP on a 346 CI motor.
That being said I picked up 10 HP with my FAST 78 but lost 6 Tq.

Yea, I like to choke the hell outta my motors. That's how I roll.
Can everyone see my sig?
it's clearly stated that I have a 415ci engine. . . a ported 90mm tb/ported FAST 90 is silly on a stock engine!!!!!
