im looking to by a programmer for my 99 dakota 5.2L 318. i know Hypertech and Superchips are the two for dakotas, i am wondering which one out of the two are the best. Do they even work? i'm looking to get back to my original mileage.

 

I have superchips. its alot better then hypertec. you have 3 settings.87 octane, towing, and performance. you can adjust your rev limiter, top speed limiter, tire size and view and erase codes too. I just leave mine on 87 octane and it gives you a lil bit better milage and you can feel a difference in power too.

 

Superchips - I run the 93 oct.program. If you are looking to get better gas mileage, not sure you'll see much.
