Hey guys I'm looking to tune my 17 3500 Cummins.

I'm trying to figure out if I'm gonna delete it or go emissions compliant.

I'm not against either.

I have a Carli pintop 3.25 inch lift on 37s.

I wanna re gear as well to 456s I think as I have 342s.

Maybe a compound kit down the road but will just start with tuning and Trans tuning.

Valve body for the 68RFE and gears.

MM3 the way to go?

Advice.
