Boost creep...

I figure if i get a brand new TEO4H with and brand new wastegate, i should be back to holding 12psi. Is it worth trying or should i just get a differnt type of turbo altoether like a super 60 or t3/t4 hybrid? I just want to elimitate the **** boost creep, its sooooooooo agrivating!!! thanks guys

I'm running a new TEO4H and wastegate and it creeps in the higher gears. I'm just going to install a 5th injector and run this mitsu as hard as it will go. Then it wont creep anymore

would adding +20% injectors help?

Only if you need more fuel. Remember: boost creep has nothing to do with your fuel setup--it's an exhaust energy problem. You can add a dozen cold start injectors and up your fuel pressure to 200 psi... but your boost is still gonna creep until you fix the actual problem.

I'm saying, in my case, I'm going to max the mitsu out so it can't go any higher. Therefore, no boost creep.
