Hello all.

I have a 2012 and 2014 5500, both automatics, and both are tuned.

One has a Second-Gen swap, the other has a stock turbo, and I’m not sure what tune I bought it as is.

I’m new to the forum and just figuring out how to navigate.

I have an issue with my 14, not building boost and bellowing black smoke.

It has been like that since the swap and tune.

I’m running a RaceME tuner, and according to them, the tune should be fine, but from reading, I have concluded that I need a custom tune.

I appreciate any help you can provide.
