FAST 92 HP results!
Well I managed to get to the dyno yesterday to have have few pulls done and have the car tuned after the FAST was installed a few weeks back. After 3 pulls, the grand total HP gains with the new FAST and stock TB was 18 RHP. Not bad? Spin really did his magic on this.

Was this 18 rwhp over the stock LS2 intake?
Please post all your engine mods.
On my engine with ported heads, ported TB, very small cam, headers, exhaust, the ported FAST 92 picked up 31 rwhp/32 rwtq over the stock LS2 intake. It ended up at 444 rwhp/410 rwtq. Of course, a new tune is mandatory with the FAST 92 because of it improved cylinder filling, less ignition advance is required. I had to reduce the advance by 4-5 degrees at WOT to avoid KR. An engine with stock heads and cam would not yield this kind of a gain.
By the way, I cut the firewall and instead of the intake to get it to fit. Personal choices but either way, its a PITA.
