Message	Did you open the throttle bodies or left the balance tube off? If yes then it's time to rebuild. I like my GT2560s but if I would do it all over again I will select the GT2860 or GTX2863, if going with the 600s buy the Forge wastegates, I think it will respond better. On 91 octane you will make around 450- 470whp with all breather mods. By the way, now its the time for the MSP exhaust manifolds. if I were you, I would definitely build with forged internals. It's not that OEM wont take the abuse but the forged internals will take more abuse. Gaskets stay with OEM, even if you bore the sleeves. There are plenty of specimen to backup my suggestion. I'm running 88mm pistons with OEM gaskets, making 571whp abusing it frequently for a few years.

However, those 550s you have are not very good - MixManMash 20:37:03 05/31/15 Yeah I know they aren't great, - platinumist 00:04:21 06/01/15 I'd do a leak down test - aliaZ 14:58:33 05/30/15 Agreed. (n/m) - Bernie (NoVA) 19:39:06 05/30/15 Very good point and I agree. (n/m) - MixManMash 10:54:19 05/31/15 Good point. - platinumist 14:42:43 05/31/15
