Best tuner for fuel mileage??

Yeah i was looking at it and it said 2-4 mpg increase

you've gotta get rid of the DPF to get good mileage and quad has the tunes to do it
 
probably works, PPE can tune a dmax but price is factor if it was me.

If price wasn't a factor, PPE no doubt.
 
Yeah i know PPE know's there stuff on the duramax's and i dont think he is going to worry about the difference between the quad and the ppe on the price.
