I was looking to tune my Dmax everything is stock on it except a cold air intake. Would EFI or PPE be better for it and with EFI live, what do you buy for preformance, fuel economy, tunes, and smoke.

 

EFI live, check duramaxtuner.com or check with one of the vendors

 

you dont have to do anything to your truck with EFI Live. it is the other way around, upgrades done to your truck; EFI Live can accommodate.

EFI Live is fully customizable. build tunes for mpg, raw HP, light HP, tow tunes, and everything in between.

i wouldn't go adding a bunch of HP to your truck with out upgrading the appropriate areas. talk to an EFI Live tuner and explain what you got and what you want and he will help you get there.

 

The only other thing I would get is an EGR blocker!! You can tune the code out with EFI live
