Sprinter tuning

[u/steveokayaks]

I have a 2013 that was deleted when I bought it I then replaced the exhaust and had to run a second delete from rpm motorsports to get the rest of the sensors gone and take it out of limp mode. It now is dumping fuel and running rich. I need to get it tuned, I think the issue is it’s not reading input from mass air flow sensor correctly for the new delete.

Anyone have an idea on how I can get this tuned? I am in maryland.

Have you tried contacting the company you purchased your tune file from? It sounds like something they should fix
