I read the last thread on timing and didnt understand it. I read that if you up your timing to about 15 degrees, you fuel economy greatly improves. How exactly do you do it? I talked to the a guy I know and he says it takes a good 3 hours and if someone did it for me it would cost about 300 bucks. Any help?

 

I think you would do it with a box on your '02... in any event, you would probably get a better answer in the 24V forum,
unless you aren't talking about the truck in your signature. I'll look around for the link to the instructions for advancing
the timing on a 12V and post it so you can take a look.

Hope this helps.
