I installed a Fast 90 and Ls2 Tb on the car today. It seems to have gave more power from 4500 up BUT it seems I have to apply more throttle when just cruising around to get the same power I had with the Ls6 setup. WOT I do not notice ANY loss of torque in the lowend, perhaps even gained some. Why do i have to apply more "foot" when part throttle cruising? It it something to do with the drive by wire setup since the TPS is also integral in the Ls2 TB??? On my old TB it also had a hose that ran from the passenger valve cover to the TB. The Ls2 does not have a point to attach it to??? What has everyone been doing?


Comments, suggestions and help appreciated.

I had a FAST 90 intake manifold & NW 90 TB, but switched to a LS2 TB due to idle issues that couldn't be tuned out. I noticed it takes a little more pedal a low speeds too... must be the LS2 TB.

i hooked the hose from the passenger side valve cover to the air bridge, just drill a hole in the air bridge and get a gromet the right size so the hose fits in snug. I have NW TB and it works flawless

Well I ended up putting a breather I found at autozone on the vent....I'll post dyno numbers up soon, after I get the tune dialed in. Oh....I also find an oil leak on my timing cover/oil pan junction from when I installed the heads. I was not to happy with myself about that one, I may just pay G-force to reseal it. Anyways Ill post the numbers when I get them in a couple of weeks....
