Pics of the 90mm LSX manifold and comments
Its the same as MTI. Nobody had any finished TBs in stock but TPIS had some 90 mm housings which needed the stuff from the OEM TB. Thats the route I went

Thanks thou. How much are you expecting to gain, I would say maybe 8rwhp on a 346
good luck
I'm a bit more of an optimist based on LGs results. I've also seen enough evidence that the TB is starting to become a restriction at my power level. I'm guessing 15 or so RWHP gain
