Need help from the tuner gurus
So this past Sunday I got around to gapping my plugs to .030 because my 5* tune was misfiring at wot. That fixed the misfires. Well yesterday my truck started running funny.
Situation. In third gear, low rpm range and giving gradual acceleration I get some surging then after a few seconds my trucks finds it's sweet spot. Fired up the handy torque app and checked for misfires. No misfires no codes. Something told me to monitor the timing. Sure enough, timing would drop to -15 until I had to give it more gas then it bumped up to the normal range. At wot adv timing is around 4-0. (Scratching my head).
Looks like this started happening after the ecu finished completing all the test from uploading the tune.
So I did an ecu reset and the issue is gone.
Has anyone experienced this with a 5 star tune(87 perf-tow)? Or know wtf is going on?
This problem does not exist stock. Thanks in advance

Pulling from the wrong timing tables. Im not expert but Shawn at SoCal tuning did my current tune and we eliminated all surging and "dead spots" throughout the RPM range via adjusting where the truck pulls from the timing tables (what that means, I do not know - but he fixed it).
Someone would have to convince me y this is happening first

Thanks for your input. I just can't wrap my head why the tune was fine for a few days and then it started doing this. And now after resetting the ecu everything seems fine again. I'd hate to spend more money on another tune and have the same issue.

If you want a tune that huals like a bat out of hell and a tuner (as in a person that writes the tune) that will modify your tune until it is EXACTLY how you like it then hit up Shawn at SoCal, Its what I run and I have had MPT and Unleashed as well.

Im assuming that the truck fills the tables I mentioned with data after being reset. Since it is pulling from the wrong tables for consistent spark advance, the truck will keep re-learning it's bad habit of surging. Purely an assumption - Has it come back more than once?

And for Pete's sake, come up for air...

Shawn fixed my surging so if he speaks to mike and doesn't get it fixed, im pointing him in the right direction.
Everyone is now getting Unleashed so my advice cant be that horrible. My post at least attempted to help while yours was not useful at all - do you even have an ecoboost? Looks like you have a trailer and a BBQ, what that has to do with an F150 forum I do not know.
Sorry for helping

----my uneducated stab---
I'm am thinking that re-gapping your plugs probably means that now you need to re-adjust the tunes based on being able to take more advance. The truck will calibrate it self and add some timing as well as pull timing even when tuned. I would datalog a run and compare them to old logs if you did it. I have found that using my SCT to datalog is a whole lot more informative than just checking knock with Tq Pro.
Side note, after re-tuning did you notice any "gray codes". I am still trying to figure out how long these things take to disappear.
