I also observed no real gains past 31 psi. IMO the hotside has become a restriction for the displacement and ethanol fuel.
Are you running the stock FPR?
Really? PTE doesn't sell a bigger v-band hotside. Imagine their engineers think a bigger hotside is not need it. EVOs make high 700whp low 800whp with this turbo 2.4L.
