Hey guys well I have an xr6t mk11 ute and iv put an intercooler and bigger injectors in on the weekend and tuned it to 10psi with the SCT tuner.(Apart from that the utes stock as a rock) Now when im on boost it keeps cutting in and out through the rev range. Anyone know whats going on or heard of this problem?? any help would be much appreciated

I aint an expert but doesnt the cat start to restrict when you start running a bit of power??? I am sure someone else will be able to shed some more light on the problem

The could be lots of things wrong. Start with the basics like

-spark plugs regapped to .8mm

-boost leak

from there come trickier to diagnose problems

-coils faulty

-fuel pump rooted

-fuel filter partially blocked

-O2 sensor playing up

Have you had it on a dyno to see what the boost and AFR's are like?

Is that 10psi tune generic or custom?

Take it to Ford or a tuner and see what codes come up.

hmm I think I might take it to a tuner, cause I dont see how my fuel pump could be rooted,fuel filter blocked or faulty coils as it was all sweet before I put the injectors and tune in, im pretty sure it was just a normal 10 psi tune, I will get it looked at, Thanks for your help
