93 eclipse gsx. engine cuts out

Engine cuts out at 16lbs boost and won't go over 5000 rpm. Replaced
fuel filter , spark plugs, wires, coil pack, and fuel pump. No faults stored.

run a boost leak test vfaq.com has instructions to make a tester

well about the cutting out at a sertain boost level i cant really think of anything off the top of my head..but the 5000 rpm i could help you with, have you takin out the rev limiter yet?

a gsx rev limeter is at 7200 so thats not the problem

oh really? i thought it was the same as the GS b/c i know the GS's rev limiter is set at 5000

I ran a leak test and found a major leak at the downpipe tube to the intercooler. It goes all the way to redline now "7200". thanks for your info.
