Has any one had any troubles with the 03 dodge off/70/120 chip?

Yes, most people who have tried them. I sent back a couple and then quit selling them. I do still have one on a customer truck that works good, but the others threw codes and ran poorly. I don't think BullyDog is selling the adjustable chip anymore either.

They are now selling a 0-50-100 horse model, also rebadged and sold as a quadzilla box. It seems to run pretty well.
