Quesion about intercooler?

[AWDTURBO02]

on my 90 gst i have a bad intercooler leak and i have a really bad fuel cut problem. the leak is not coming from my plumbing i think i have a hole in my intercooler also i am boosting at 16 pods when i hit 10 it goes n wher and my boost is at full. what do i do get a new intercooler? and should i buy bigger injectors?

Fix the leak. Pressure test the system or you could take the intercooler to a radiator shop and have them pressure test it the same way the do radiators. It is possible to epoxy a leaking intercooler or you could buy a used unit cheap or now would be a good time for an upgrade. Your profile says your car is stock so injectors are not needed at this point.

Agree... It shouldn't be that hard to fix your existing IC...

very easy depending on the size of the leak. first i would pull that stock ic off. Then i would clean out the inside with some gas (there is a vfaq about this). Then pressure test the ic to make sure that is you problem. If there is a hole, JB weld does wonders. Make sure the area is prepped good, sanded down and cleaned off. That should do it for you. Let the Jb weld cure for a day.
