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. This post has been edited by urbandork: Jan 30, 2006 - 3:32 PM |

if you hit fuel cut you should see the Check engine light come on (if you do have a working check engine light)
otherwise it could be a timing issue or a missfire (i'm leaning towards missfire but i can't be sure) ... do you have an EGT gauge? do you know how to read your plugs ? a ball spring won't fix the problem... what fuel pump are you using ? you could be maxing it out, or have a bad fuel filter .. (since it only happens at higher demand) just a few things to check -nuke -------------------- 2005 MB C200 Kompressor- K&N, Apexi WS2 Catback, DIY Voltage stabilizer, Intrax Springs, H&R RR swaybar, VDO Boost Gauge @ 6psi, Greddy L7 plugs, +0 Rear tires
