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...
i have 2009 GMC 1/2 5.3 3.73 it has gauges for water temp, tranny temp, oil pressure. would this scan gauge work better for me. also came with tow package, which includes trans cooler. someone told me i might want to upgrade to larger. should i thing about it. also, would cold air intake benefit me
