Smarty Jr and Tach
I let a friend borrow my Smarty Jr for his 06. We loaded the performance tune and his tach quit working right afterwards. We took this truck back to stock and his tach works intermittenly. Anyone have this happen to them or could it be just a coincidence that his tach was getting ready to go out? Other than that, the performance tune works great. I pretty sure he will be buying a Smarty Jr very soon.
