cuting under load...

[jaden]

ok heres what happened... my car was cutting a while ago so i put dsm link in it. I started tuning it and i had it perfect untill today when I was driving it WOT it cut out like i let off the throttle but it was on the floor so i let off and now whenever i put it to the floor its cutting out... seems like its almost cutting right off. some things you need to know...

car:
91 talon tsi awd with jdm motor, dsm link, evo 510cc injectors, 3 inch exhaust, headers. 60 trim turbo, f.m.i.c, 2.5 hardpipes

i logged it on dsm and it was saying i was estimating i was making like 50lbs of boost and i know its only about 10psi in reality

airflow level was through the roof... cant remember exactlly how high. put piston rings in it about 3 weeks ago and a mitsu mls HG and arp studs but forgot to re torque. could that be the problem? blew the hg after i forgot to re torque it?

what psi are you at?
if you have the stock fuel pump, but all those other mods.
it could maybe be fuel cut...

Sounds like either an ignition misfire or you are getting fuel cut. What maf you running.

sorry forgot to mencion that... after it started doing it i was suspisiouse* it was the 3" gm maf in there so i put the stock one back in and it still did the exact same thing... and i was running 10 psi when it happened but i bypassed the boost controller so it should be only about 6psi now. did a boost leak test aswell, it leaks but its vary minimal and you cant hear any leaks

and stock fuel pump but that shoulden't matter because it ran perfect before it happened...

to solve this thread... it was the turbo getting bad on me. it ran worse and worse.... than for some reason better for about an hour and than completly died on me. it had about an inch of shaft play after that haha
