i dont know much about this, but i've always heard the F150 transmission "learns" your driving style over tyme and makes adjustments as it sees fit. Does the gryphon with custom tunes still allow for this or disallow? i ask because it seems this learning business is un-needed i.e. from the dealer lot the tranny would shift just fine but get worse from there on over time. I had brought my truck in to get reflashed after a couple months and it was fine again. Since then i have the gryphon with custom tunes and of course its even better, but hence my question.. will it stay this way or will this truck try and learn still. Wish it wouldnt.. its a bad student
