hws the turbo holding up? Will be running a 7psi spring + mbc.. my question is can i adjust the preload with compressor to open at 8psi and use mbc to hit that magic 10psi just to avoid that boost creep.. if that make sense?
I don't know other car's turbo setting, but in this FR-S, boost creep is due to too low exhaust back pressure. for example, if you use catless 3inch full exhaust, you will suffer from boost creep. I didn't experience boost creep with my exhaust - 2.5 over, 2.5 front pipe with HFC, 3" cat back. and yes , you can avoid boost creep with low preload + MBC. good luck =)
