gas or diesel?
12/14/2017 at 7:36 PM
what year/make/model? do you have a gas or a diesel? there are several plug and play tuners that are compatible with gas and diesel. they get downloads from the internet and some can add 15- 30 horsepower. bullydog , superchips, and diablo are some popular ones. talk to a parts/accessory dealer. they plug into your diagnostic port and change settings on your pcm. becareful as some manufacturers may void warantee if dealer discovers pcm has been altered.
