boost leak?

[GSTdsm_97]

okay dont hate im trying to learn, i think i have a boost leak, my gst is running on 15 psi with a 16g and all greddy pipeing front mount and bov, but i noticed today goin down the highway i did a pull and once i hit about 85-90 mph on about 12 psi my car shutters fot a sec then quits but drops a little boost but when it gets to 12 it does it again ? boost leak? like i said dont hate im learning thanks

Definitely do a blt (boost leak test) immediately. And the stuttering Could also be a culprit of bad spark plugs, or bad wires, or bad incorrect spark gap. Maybe your running rich?

More than likely.

it does run a little rich but not alot , im just tryin to get it through winter and this summer its getting a major tear down and and a lot of things fixed, but thanks like i said im trying to learn but u ask question like this and some people are just ass holes

Yeah run a boost leak test and check your spark plug gap. Make sure its gapped no bigger then .028".

Depending on your boost gauge it might be slightly inaccurate and you could be hitting fuel cut with that 16g if your still running stock injectors

thats what i was told today from my buddy that has a gsx and its more then likely fuel cut, and i do have stock injectors, i did a boost leek and there was just a very small one by the intercooler just tightened the clamp and it stopped, thanks !

get some bigger injectors and tune it, use that 16g to its full capability
