chips

When there was a significant benefit to it, chipping and tuning gas engines was popular. As the factory performance improved over the years the benefits of aftermarket tuners decreased to where you don't seem much of a market for it anymore. Diesels used to be real sleepers with a lot to be gained from aftermarket tunes, even more so than gas engines. Seems the factory is doing much better now so the potential improvements probably don't outweigh the downside for most. I think we're about to the point where tuners are a thing of the past. If not for market reason, OBDIII will probably make them impossible to use without being reported.
