New code problem...help?

[Waterloo]

What kind of tune do you have on it? Do you know who wrote it or who installed it and where? Is it a tune associated with this site? If not, I would pull it and have the programming inspected, Rawze has been doing that for guys to see what they actually have, and the potential damage that may be happening. Do you have Insite? You are going to need that, as this code could be a few things, including a failed or failing fuel pump. Maybe someone else will chime in... Sounds like a questionable tune.
