20 3.0 ecoboost tune review?

[pooleo]

Can the community help with looking into this tune? Its been great but theres one issue. While gently accelerating normally, once it gets to 5th gear and around 60-65mph, if you keep gently pushing on the pedal to keep accelerating, the vehicle snaps your head back and takes off like a rocket. The best comparison is like a power band on a 250 2 stroke dirtbike. it goes from about 80% throttle right to 96% and what i assume is max boost, about 36psi according to vcm scanner. If ya dont let off the pedal it throws a p0068 code and goes into limp mode. It takes about 2-3 seconds in real time to trip the wrench light. Its completely fine if your driving wtfo. Its the casual DD that its an issue. And forget about towing a 3k lb trailer......jesus

I can't check it out since I don't have the definition file, but it sounds like an over boost issue. Check that section and see.

Next time I'm around an MPV I'll download it. A log would be nice as well.

Make sure your OP thresholds aren't too low, same with the hysteresis. Only other thing I can think of is a very aggressive tip-in boost strategy. Driver demand/torque tables can throw things off like that as well.
