2002 Silverado Tunner?

I can't find any newer posts on here.

Who do you think does a better job Nelson or Wheatley?

I'm just looking for better towing power and mileage on a stock truck.

5.3/auto
3.42 gears

Thanks!

hate to see your post with no help for several days already.
i think, you need to explain better what is that you are looking for? Tunner? tuner?
you will not get better mileage with power mods. forget it.
