I dont know what tm yall are running, but my smarty feels great thourghout the throttle position. If your transmission doesnt like it, because it fuels so good on the bottom end. I bet you can detect your PPE by the dealer! I have had more problems with a tst than any chip ever used. Always throwing codes, truck running bad unexplained problems. With the new downloads for the smarty EGT's are way down, smoke is way down, power is awesome. The Smarty has so many different programs availble for you to custom tune your truck just where you want it. Bottom line Smarty is constant thoughout the rpm range, I don't understant what you mean when you say once you learned how to drive with it. It feels stock just way stronger. Not to mention Bob is wonderful customer services, and nothing means more to a customer than service after the purchase!
