Was this on the same dyno as the first #'s? Same tuner?

It may be because you now have a stout intake going into stock LS6 heads...I usually see FAST intakes on at least Stg 2 ported LS6 heads. You really need a set of great flowing heads to maximize the gain of a FAST....So it almost sounds like a slight mismatch in parts. Just IMO

I also have a ported FAST 92, that I got Powder Coated to look nice. I installed a Lingenfelter 90MM TB. My car is so torquey!

so youre comparing your 'new' dyno results with the Fast90
to results you had on a totally different dyno?

might as well chunk any comparo youre trying to do out the window.

the only way to make any kind of comparo is same dyno, similar day.
