DickWells, just curious, when it failed to upshift, what level were you running. Apparently my ooooold simple model without monitor has been much more reliable, but I will probably grab the first good control module for my 02 next time I find one at a swap meet or something like that and get one of John's tunes. Does the Kennedy tune come with a five way switch now or just the two tunes? I haven't kept up lately with the latest, too busy. With fuel prices like they are now, I hope someone it working on a detuning setup for 30 MPG for my daily driving, I'd give up some horsepower for much better fuel mileage if I knew I could get it back with a push of a button.
I've actually resorted to cutting mine back to level one and then setting the tow haul mode to level 4 in case I need to pass someone really quick. Has worked good so far.
