your going to hit fuel cut around 10-12, the stock turbo can only handle 16 psi that is if its good.

i have an upgrade ct26 with 60-1 trim..im not worried about the turbo.. iwanna know what the motor can handle before it will mess up.. ill have 550's safc walbro and lax afm.. all i want to know if how much boost can the motor take..

Don't plan on getting an FCD and turning the boost up. You'll blow the motor. An FCD is kinda like having a friend tell you drugs are good, mmkayyy. Before you know it, your fried.
EDIT: You could blow the motor.

What in the worthless questions to ask....

First, get that 'max boost' crap out of your head. Boost = pressure in manifold = resistance to flow.

What are your power goals, and what do you want your torque curve to be like?

Never look at a turbocharged system as just 'how much pressure can I run'

That said, just how much pressure you can run, depends on a hell of a lot more variables than just what motor you have, or what internals - what are you using for engine management?

If you have a properly installed MHG, boost is he least of it's worries (the gasket). You will blow something else up before a properly prepped and installed MHG With ARP hardware will go... If you don't believe me, ask a few on here who have done this (IJ. for example).
