I have a 2015 powerstroke and after installed the tuner my factory exhaust brake button no longer worked. It worked great before the tuner. I tried updating my tuner and that didn’t help either. Has anybody else ran into this problem?

Also what tuner are you using on that vehicle?

If you return the truck back to stock, does the exhaust brake work again?
