I am looking to buy a tune. I have a basically stock truck and transmission and I am looking for a tune to give good gas mileage and another for towing about 8k. I have a Smarty 06 right now set at level 3 with pods at 80 and it smokes bad, I am too old to roll coal. I want to keep my PTO and tire size adjustment, running 33" tires. What is out there? Thanks
