i was looking at getting a tuner after my tax return and i was looking at jusnes websight and saw the used ones. i know they are not makig them anymore but how do they work, i dont want anything to fancy but something that will help my truck out. and can i change the prograns for like 87 octain power and one for 87 economy and then one for 97 performance or do they have to be the 3 that they list?? will i notice much diffrence with the tuner with my older 4.0, has 96k on it now and crapy gas mileage.

thanx

basically they or you will contact doug and the 3 programs will be built specifically for your truck.

 

And yes you will notice a big difference..

 

is that programer good enoufgh for just the power use i dont really need the scales and all that, or does the other newer tuner have more power capibuilities?

should i be fine with that one?
