Hmmm...
GTi-R T28s do hold more than 16 to 7500 redline, the last month I had that turbo on my car, the wastegate went bad and it didnt open, and it held 20psi till rev limiter...
I miss that, car felt really good, ran good, even tho the AFRs were at 13.5 at WOT hehe... Ran like that for a month and never had an issue, still amaze me how much a stock avenir DET can handle...
Now I want to boost 20pounds again, but this time with meth injection and Torco to up the octane to like 100octane, and a bigger turbo with bigger injectors, dont want to push my luck that far again
