Just wondering what some of you 7.3L guys are using for a tuner to improve towing performance and fuel economy?? What's good and what should i stay away from? Thanks..

Ran a superchip for a few years on my early 99, then went to custom tunes by DP Tuner, night, and day difference in performance from the Superchip, can't say it improved my mileage, but I was after more towing power. The 7.3 is a dog stock. I added 4" exhaust ,gauges ,and an AIS air filter. The truck ran pretty good, but still lacked a bit in power towing heavy, but upgrades did help.
