Fuel cut ???

[zoonwen]

I hit fuel cut when i 1/2 throttle, im guessin my w/g is crepping. I have a front mount and straight exhaust. Whats the best solution to solve the fuel cut issue ????? :wtf:

Most likely this is a boost leak. Check all your couplers, vacuum lines, everything that could be leaking boost...

when I boost I spike at 14-15 psi, wouldnt a leak keep it from boosting high ??

[GrimJack]

Nope. I had a leak, I could still boost to 14psi. The leak had to get pretty bad before I had problems boosting. As in, I had a crack almost all the way around the coupler from the 3000 pipe to the throttle body.

umm if youre hitting 14-15psi that is normal fuel cut for a 1jz map sensor...to fix this you will need a 2jz jdm map sensor...

what is the best way to keep the wastgates from creeping ???? I heard that the wastegate port is to small on the 1J and it dosnt allow enough flow to keep the turbos from spoolin up.
