Ok so I've been reading about MBCs and the general consensus is that they're bad. Now I'm running stage 2 and I plan on getting protuned soon, and I was wondering if upping the boost would benefit? I'm going to be getting a bigger TMIC and walbro fuel pump before the tune, but would upping the boost hurt the motor or turbo?

Let me hijack this thread for a minute.

So is it the general consensus that the stock turbo is no good above say 15 or 16 psi toward redline?
