So we got some dyno time in this morning and boost seems to be falling off at 5krpm, its not spark blowout or valvesprings because i even backed down the boost a little and same issues remains i even icreased timing a couple of degrees and nothing and its not breaking up...
I didnt hook up an exhaust backpressure gauge yet but im sure that the ratio is over 1:1 cause its a 418 with a t6 on a 1.08a/r exhaust housing.. I think i need a stiffer wastegate spring because its only a 7# spring and im sure as the rpms increase the added backpresdure is pushing the gat open resulting in lost boost...
Wut u guys think, am i aiming in the right direction, ill get the graph up in a little, u can see it crest and then start to fall of around 5krpm

Lol i dont believe in corrected numbers, this is how much power it made then and there, i dont think people correct their 1/4 mile times when theres a low da and the temps are cool outside so y should u do it on the dyno, unless of course ur doing it for tuning wise
