car isnt feeling as fast as usual dont think its just me being bored with it, doesnt seem im building boost like i use to also, seems to just cut off at 4 instead of 6.5 just seems laggy
yes i have a boost gauge thats why im saying its only building 4psi, should be around 6.5 boost leak makes sense also exhaust leak could be a problem too ugh
When I first built my engine, I kept blowing the hose off the volute because there is no lip on the end. I was able to make 5psi boost with the output hose hanging off by 1/2". It was noisy when I was driving. If a good visual inspection doesn't reveal your problem, you can pressurize the entire system. Put a disc or cap in the system to block the throttle body end of your plumbing and cap off the other end with a fitting in the cap and put pressure across the plumbing using a compressor with the regulator turned down to help reveal your trouble. Your BOV could be stuck open, loose plumbing, torn hose, hole in intercooler. Give it a thorough inspection!
