I know that gauges should be the first BOMB that goes on a truck, but I am in the market for a truck and not everyone believes that, so here is my question? I am looking at a 98 12V that has a #10 plate and injectors (the guy didn't know which ones
) It has factory exhaust and no other mods. Should I be worried that he may have run too high of egt's or is it probably ok. He said he never pulled very much with it. It never even had a brake controller until recently.
I know you guys want more info on injectors, where the plate is placed, and so on but this is what I know. Any guidence would be appreciative.
