M35 Blowing Smoke >4K Rpm, Hesitation Around 4.5-4.75K

It was a decent leak, no wonder it was blowing fuel out the zorst the last 4 months.

A quick pressure test would have found it in no time.

I finally got access to a workshop and compressor - but we couldn't find any leaks under pressure, we replaced some pipes and worm drives for good measure though - it's all nice and tight now but the problem persists.

He did do a pressure test! makes me worried about my black smoke now lol

Dunc has the black smoke completely gone?

We did try a ghetto pressure test but Id say the bung wasnt good enough. Definitely needs to be specifically crafted for the hose you're fitting it to

Very stoked.

Probably not 100%, I'll need to throw a gopro on the back again to confirm - but I'd say there might be a couple of rich spots in my map (Untuned, highflowed turbo) but its not like it was in the youtube clip any more; any black smoke would just be if you were looking for it. I can rev it out to 7k at 17+ PSI and theres no dead spots after gear changes.

If you haven't pulled the hose off on the passenger side after the FMIC, do that.

:squint:

So any tips as to what specifically between the AFM and TB might leak?

Try the hose between the intercooler & turbo...

I can see you posting, but all I'm reading from you is "I sold my Stagea and now I'm a lesser man"
