I bought the superchip programmer frm superchips for $480. I set the programming to performance but didn't really see any gains. Nor did I feel any oomph. Has anyone bought the 3715 programmer and found themselves w big gains??

 

What motor does the truck have?
Does the truck have any mods?
Are you using 91 or better fuel?

Im actually running 93 octane from BP. I have a cold air intake and soon to have throttle body spacer and i have a flowmaster 40 on the truck.

 

oh and i have the 3.9L v6

 

18hp and 29 ftlbs of torque
This should be noticable.
Run a tank through and full up with as much premium as you can, if you still do not feel a differance.
Give one of our guys a call and we will have you send it to us and we will check it out.

When I installed my superchips programmer, I felt no change except the delayed shift. But I gave it about 100-150 miles and could tell a difference. I believe your computer and engine have to adapt to the change.

 

When are you guys going to come out with the 05+ 4.7 tuner? Can I use the older tuners with for the same size engine with my truck?

 

yep! I disconnected the battery for 20 minutes and then connected it again and started it right up. huge difference in performance!!! and now im getting 20 - 22 mpg of really fast driving haha. I just bought a throttle body spacer, I wonder if it will work like they say it does.

 

two differentcompanys have one for 3rd gens. jet perfomance and i think the other is hypertech
