That scantool looks like a nice toy. Thanks for the link.
I spent $100 bucks last week at walmart and bought a code reader. The scantool looks a lot better. I was in a hurry to get my truck back on the road.
How does that virtual dyno work? Does it give you freeze frame, on the road data?? The code reader that I bought does that but only with a trouble code
what gears do you have in your truck?? My diff. has 3.7 My dad had a 3/4 ton chev with a 454 in it with 4.11 gears. He got 9 MPG running empty or pulling his 27 FT camper.....????
