I am hoping to put down around 1200whp a 7675 Gen2 Turbo and I got duel Tial MV-R Wastegates. Can anyone share what springs I would use/put in if i'm boosting 35+ psi ?

I am running pro-efi for my engine management and most likely will have E85 for my high boost settings with the exception of a normal pump gas tune for 16-18psi.

Thank you,
