Wastegate rattle with downpipes~

soulja620 · 05-05-2011, 10:01 AM

A couple months ago, I installed my jb4 and downpipes...

During initial start-up i heard the "rattle"
While cold but would go away as the car warmed up..
Over time it has slightly gotten worse...?

I recall reading something about this rattle going away with different firmwares?

Either way, I'm assuming its a horrible idea to take my car into service with downpipes complaining of wastegate rattle...

But the last thing I wanna do it take them off =\

Unfortunately, you'e gonna have to. Unless you have a very good relationship (have beers, shoot guns, get hookers with, etc) this will not go well for you.

The Procede is the only software I know of that will adjust the wastegates (open) to alleviate this issue. Terry has stated he will not alter the JB4 firmware to mimic what the Procede does.
