fuel cut @ low psi

[relax]

well like the title says i am hitting fuel cut at 7 psi with my Greddy Profec Bspec boost controler and thats with it just turned on (no boost is being applied). when it is turned off i can hit the stock 7 psi without hitting fuel cut. the boost controler worked before i installed a new ic with hard pipes i was boosting around 9-10 psi. It seems to happen in first and second gear right around the 3k r.p.m so i have no idea what is causing this. i searched but really found nothing like this unless i was not using the right key words. so if anyone has any idea please tell me. also i plan on testing for any boost leaks this weekend

Are you sure you hooked up the boost controller correctly?

If you know you hooked it up right then it might be a small boost leak somewhere....

 

[aye mate]

boost leak is my vote.

boost leak is my vote.

Word... my truck had the same issue, ended up being a hole in the I/C!

yea i am sure i hooked it up correctly but as to the boost leak i think thats what may be the issue so i plan on doing a test to see where the leak maybe from

you said you put on new a new Ic and Ic pipes, so I'd check the couplers on all the ic pipes.
