I had posted the same problem in a earlier post. I do not have a FFV truck, it is a 08 4x4 5.4 totally stock except for the Gryphon with canned tunes only. Surge on level 2 and 3 on very light acceleration.... Might be there in level 1 also but it could be just because I am looking for it! Going to order custom tunes but am not going to add any upgrades to my truck.
