I ran every tune extreme,80hp,50hp and tow. Each one was run for two days and every trip made the truck cycle regen and stayed in it. I have gone back to stock and have given up. It costs way too much when the truck is dumping all that fuel. Time for other beta testers! Just hope you never get the L30 flash!!! Good luck
