Not to be rude or anything but that's a lot of money spent for 415WHP at 8 psi. You sure there's nothing wrong? My GT-R turbos made 460 whp at just under 9 PSI (wastegate pressure so its 7 PSI at redline) on 93 octane. Seems like your tune might be off?

There may be a number of reasons. I haven’t seen the dyno plot yet, only been told 500 bhp which I then naively converted to 415 whp under assumption of 17% tranny loss. I have NOT been given the actual whp yet. Also, our dynos may differ, as well as, correction factors. I have yet to see which standard was applied
I also run cat’ed downpipes.

To be honest man there is something wrong with your tuner or build....I just completed mine in Korea and got 542 whp with my AAM kit...You should easily be in the 500whp at the very least high 480+ depending on exhaust downpipe and what not....I would honestly get another opinion on you tune....you sure they are not holding some information out from you? Did you go with the small boost actuators for your turbos? honestly there is really no reason why you should be running that low on boost...just my opinion
