Am thinking about buying a scan guage D for my "01 Tradewinds LTC with the 3126B Cat 330hp turbo and am wondering what all it's gonna be able to tell me. Does the computer actually read all the things...
As above, I've had mine about 6 years. Took about 2 months to get MPG calibrated. But now I actually get .2 to.3 of a mile per gallon better if I figure it by hand. I'm O K with that!
