ISX Horsepower/Torque setting

It sounds to me like he let a stealership that was clueless feed him a long line of bullshit. As stated over and over on this forum dealership training only teaches you enough to get by, (I’ve worked for them and that’s exactly what they do) on rare occasions you find one mechanic that won’t settle with just what they are taught. Not to mention the guy was probably talking to a salesman….. who’s job is to sell, get where I’m going? Send me a pm with some contact info and I’ll do my best to help you out there is more to your questions than you are asking.
