ok well i got my spec stage 3 broken in and so i cranked up the boost till fuel cut.
im one of the lucky few that can get 14psi! WOOT!!! well, after i punch it it goes to 14 and stays for a while and then falls off to 13,12,11 and stays.
what i was wondering, can i shim the wastegate and it will stay?
i got a mbc.
The stock CT can't push 14psi with the amount of exhaust energy being produced by the motor at that RPM. It just can't keep up. Shim it all you want, but it's not going to make any difference. Be glad you can sustain 11psi.
ok well...i shimmed my wastegate with washers from the stock head bolts. 1 on each side.
but im getting kinda scared to though cuz i havent seen fuel cut yet.
when i get it fixed i will take a pic of my boost. its like at 15 1/2 when i punch it and then it goes down to like 14 1/2 then 14.
it was about 75° last night.
last night i went out and boosted it and it pulled crazy and then i poped off my 3000 pipe to my throttle body and it was late and i coasted to my house for like a 1 mile!!
i havent fixed it yet.
You must either be really lucky or have an innaucurate boost gauge! That is alot of pressure for the stock turbo to pound out - sounds like you need to fab up some hardpipes. I hope you don't boost like that all the time.
I wouldn't run that much boost on a stock CT w/ stock IC pipes just not efficient and more importantly you run the risk of running lean with the stock fuel system! I run no more than 13psi with the stock fuel system, i.e. pump FPR and that restrictive J-tube. But thats my preference.
