Jet chip has the 89710 for the automatic and the 89715 for the manual trucks.

 

Do you have a web site for parts?
or a web site or phone no. for Jet chip?

Thanks,
Rick

 

Below is some text from a site describing it. However, it looks like its more for power torque, thus, MPG would probably go down, right?

In the diesel world a few extra ponies means the truck works less to go down the road. I dont know how your truck would act with this module. We have a friend in NM that has one in his 96 chevy 1/2 ton and loves it. That is the extent of my experience. Sorry.

 

No apologies needed. its good info - thanks.

the truck doesn't have a tach and without that, i can't really tell hows it working so i need to get one of those, then i can try some of these things and know more.

its the same with the large tires i have. i need them to be a little smaller and it would probably need less power to turn them. (the truck came with 33x12.5 16.5 BFG AT knobbies...)
