After a long year of fighting problems i think i got it!car was breaking up last year on dyno at 5700-5800 now i see rev limiter at 7500 with more than 18 lbs of boost.Old numbers were 480 at flywheel 407 rwhp ill post new numbers after monday as long as everything goes right.
We're short of some technical information/questions in your above post, so we're going to move this over to the "SVT Talk" section instead...
well still problems !the shop made 430rwhp but had to tune it back to 417rwhp because they said my 90mm lightning mass was maxing and going lean.so i guess its back to the drawing board
