Did you end up doing that smoke test? Could still be a line where you can't see or a failing IC pipe connection

I did blow through a lot of lines with a vape but I didn't find anything. I have an aftermarket Intercooler, it looks snug but I'm still going to pull it out and check connections. I first got the code when tuned for precision raceworks coils but I don't see how that would cause it. Today I removed the option on mhd and tuned to v9 beta maps and checked the rear vacuum line but it all looked good

When you did your smoke test, where did you connect it to?
