When im runing 7 psi everything is fine. but as soon as get up to like 10 11 psi my eninge gets all wacked out.

at 10 11 psi it makes a really bad sputtering sound, jerks around and loses power. Is this the 2 bar map sensor doing that boost cut, is it cutting fuel?

i have an mbc on it because before the turbo was only doing like 4 psi. I had to take the cap off the nipple on the second pipe of the waste gate to get it to do 7 psi. Now i have it caped off with the mbc set at 7 and have problems with it when i get up int he 10 psi range.

u have u btm at 3?! u only need to set it at .50 -.75 not even a full turn cause ull retard ur timing so much it wont even run at high boost and thats what it sounds like.

no no it starts retarding at 3psi my nob thingy is like .5 per psi so at like 8 psi im retarding 4 degrees. Now that i think about it its acutally a lil below .5

urban, is it RPM dependant or boost dependant?
what octane fuel you run? 91?

91

and im not sure if its rpm or boost

it only happens with hi boost when it reaches 72 kpa/.72 bar/ 11 psi ish but i notice that it happens when i punch it from a lower rpm like 3k or so. Ive also noticed that it sometimes happens on the freeway when i punch it too

it doesnt happens all the time.
