So, I had to take mine in for a reflash from Ford b/c California sucks and will not let you register it next year without it. I am waiting for my new tunes but did not want to let the truck sit all weekend without running it so I went to the bank. It went into regen and what a load of crap that is. The EGT's were really high and white smoke everywhere. How can wasting that much fuel be much of an improvement in the Smog development of the truck? Anyways, I guess the truck is parked till I get my new tunes. By the way, mny DPF is on there, but it is gutted.
