Yes mine is also a flex fuel. My truck was built late 08 so I guess it already had the latest flash. Its not a real bad surge but its there. I can really hear it in the tone of the exaust when it does it, sounds like i'm getting on and off the throttle.

How's this...
BOTH of you guys are running RXDG6B4 calibrations. Curious, don't you think??? I am looking into what exactly is going on with this particular calibration set and see what we can come up with. Stay tuned.

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.
