boost leak?

[drift_raptor]

hey guys i have a 1995 gst and so far am pretty happy with the car. Ok so here is the thing. When i step on the gas(i.e getting on the highway ect.) and the engine revs above 4k..it starts to sputter and it seems almost like it wants to stall. I think the air/fuel ratio is way WAY to rich. but the boost gauge in the car, not installed by me, says i am at 12 lbs of boost. any ideas?!

note: i bought the car a week ago, it has a ingen intake, obx intercooler<<stock intercooler pipes, greddy blow off, 3 in. evo exhaust<<no cat converter,

Clean your MAS with brake cleaner

Definitely check for boost leaks and pre-turbo exhaust leaks. Change the plugs too if you haven't already. My car was stumbling and hesitating earlier this summer and a simple tune-up (changed plugs and wires) fixed the problem.

ok so any way a lil update, it only starts to stall in boost. so im still not sure what the problem is but any help would be loved

+1 for the test and plugs. My car would hesitate every time i hit boost. I just changed plugs, so I changed wires. Problem solved
