If I were you, I would throw the chip out and go with a programmer like superchips, or even better a custom tune from blackbear performance. I would go with the Autocal.

Welcome aboard

Move into the 21st century. Chips are out. Get a custom tune from Black Bear Performance

Ya there is a super chip on it right now its pretty old I got the truck from my buddy I don't want that chip that is on it. What all does the tune up do for it?

They will use software called EFI Live, or HP tuners...it can shut off power enrichment delay, shut downstream 02 sensors down, advance your timing, play with all the torque management stuff, set shift point, torque converter strategies, shift firmness...pretty much above and beyond any "canned" tune is capable of...many other things plus data log as you drive. So you can check on how your engine is functioning as well. It's actually the smarter choice, I've also heard the 8.1 really wakes up from a good tune...where are you from?

I'm from Utah I'm new to working on my own stuff so I'm still in the learning process but i do wanna tune it to see if it helps mileage at all. Do you know prices on tunes?

Hands down an in person tune from justin at blackbear performance.. youll be amazed the results you get..no handheld tuner will come close..Trust me! ive had 2 8.1 trucks custom tuned in person by him and on the trip home i picked up 3-4 mpg..besides the slight performance increase..what was most important to me was the things he could remove..like the 30sec full throttle delay! and also cleaning things up the the motor/truck ran bettter, more efficient. the autocal and data logging tune is good but in person is the best way to go!
