Well... recently i have come to notice that my car intermittently has trouble holding/building boost. best case while i am driving i will rarely see over 5-6psi in first then it usually holds around 10 in every other gear wot. but other times i will see 5-6 psi in every gear and if it does hit 10 psi it will gradually drop off to 5 psi while on the throttle or it will spike to 11 or 12 psi.... I am currently building a boost leak tester for my compressor so i will test the intercooler for leaks soon..... What could this be??? how can i properly test the stock twins? Also i believe they are on their way out because they do smoke alot.... is this a symptom of dying stock twins???? :cry:
