I found 3 tiny pin holes in my custom built SC top, I know that boost leaks usually makes a car run rich under boost, but my car is running way lean now like 17.5+ AFR under 18lbs boost 4,000 rpms. I have to hold off till Monday so I can use the tig at work to fix the holes in my top. Could this be the reason my car started running lean? I did pressure test the top after I made it and it was fine but I think that the powder coat was sealing the holes and after it got hot the powdercoat gave out and now it leaks.
