boost creep

[blackmica08]

im getting boost creep to almost 22psi reaching all the way to 6000rpm but when it reaches 21.5 to 22psi i get boost cut. i installed a turbo smart manual boost controller (boost tee) and its set almost completely close plus i removed the spring and ball as instructed in the installation manual when getting boost creep but still i get the boost to creep to 21.5. im running a veta103 map at 93 oct for a gt2781 turbo set at 18 psi. my questions is if instead of running 93oct i run 91 oct will the boost not reach 22 psi it will fall back to maybe 19 psi or 20psi?.

I don't know the answers to your other questions but I do know if you run a lower octane will increase your chances of detonation.

You need to talk to tvissues. He experienced boost creep w/ an atp turbo. His turbo is larger than the one you are running, but he was experiencing creep and did not have a forged motor. End result, his motor blew and now he at "square one"!!! Here is his cardomain site: http://www.cardomain.com/ride/2536158/6

I do not mean to scare you, but this should be a major concern for you.

you cant use a MBC safley with oem computer. The only way to fix the creep is actually set your boost level in 5th gear, but then 1st -4th will be too low, and vise versa. with your MBC it will make more and more boost as the engine load increases, Been there done that--->> get tuned instead.
