huh? i have a Precision SC-50---- 54 trim t3/t04e .63ar exhaust .60ar compressor stage 5 wheel and i only lag to about 3800ish....matter of fact full boost just over 4000rpm.... I love it...its a pretty nice powerband.... no to mention i have a greddy intake manifold and hks 264 cams....that ups it even more....

PS im running a Full-Race topmount race manifold....that helps with lag alot....the collector is HUGE and its designed so well....they say the fullrace manifold will give a 800rpm drop in lag time as compared to a log style. I'd say keep the turbo and get a fullrace mani
