Why is that? I see tables in SCT that HPT doesn't have and the other way around. Livernois has an in with Ford that neither SCT or HPT or COBB seems to have.
It's not apples to apples, but I saw folks claim the same thing when Ford put out the cam phaser TSB flash for the Gen2 3.5's. Folks, including tuners were saying "there is nothing in this update other than shutter control changes", which wasn't the case. They just couldn't see all the changes.
In this case, the only changes Ford has made for the performance tune that can't be seen in HPTuners for example are for unrelated items.
There's 3 parameters changed that change the rate the engine speed limiter cycles.
1 parameter that is normally used for overboost logic that was adjusted (not sure why, both the stock value and the Ford Performance value still leave overboost logic disabled)
1 table that effects dashpot control slightly.
There are 2 transmissions tables altered that are non-visible, but everything adjusted on the transmission side is
only for raised or removed torque limits to deal with the higher torque of the system.
Nothing is changed with scheduling, shift pressures (besides the obvious higher torque = higher pressure, but thats stock functionality), or timing.
The "effect" people are feeling is simply the adaptive reset that occurs during flashing.
EDIT: see my next post, it could also be some changes that happened from updating to the latest trans cal from an earlier MY cal
