Message well to begin I had my tb02 turbos upgraded with a 60mm compressor wheel, balanced and housings machined accordingly. guy did an awesome job.the reason was because my megan manifolds cracked on ps and caused turbine wheel to get chewed up. so now I have a set of fresh rebuilt t28's. they spin freely and tolerances are nice and tight. since my megan manifolds r no good I slapped a set of factory manifolds on with the t28's, that's all I did as the turbos. ive already upgraded intercoolers, piping, 61mm tb's from rob z. megan downpipes and test pipes, 2.5" catback exhaust with x pipe.dual maf with selin translater, 255 fuel pump, oil cooler, and anything else u can upgrade ive done, turbos were last. with tb02s my car got down , turbos spooled quick as hell, etc. since putting the new turbos on with stock manifolds they don't spool worth shit, cant get them past 15psi. if going like 60mph and I step on it they just hand at 2 oor 3 psi or climbs so slow. car doe seem quick but it seems as though they r restricted and im wondering if the stock manifolds might be the issue. no boost leak I could find, oor vacuum and no codes. im stumped here
