Need a little help or assistance possibly. I have an 86 GN with Turbo tweak chip, siemens injectors, stock turbo, adjustable waste gate, stock IC, built trans, and rear end.
so the problem i'm having is under full throttle i'm having the car pop back and causing 25psi of boost, should be only around 20lb. I have noticed that it seems as if maybe when it pops that its kicking the vacuum hose off of the Turbo? not sure if this hose set just went bad or if its something else? i checked the 2 other vacuum check valves on the driver side of the intake and the one going to the vacuum canister. i know that little hose set from the wastegate controller with the Y on it can be pretty problematic but i DO NOT know what it is that goes wrong with them? and is it worth buying the original style or just replacing it with a new Y and new hoses and having to route them so they dont get melted? any help would be appreciated!
