My tuner has been having fits with the driveability of my build. Parking lot (1st gear) was a nightmare with jerking and bucking. Coming down through the gears on decel to a stop was also a problem with the truck almost always stalling at the bottom of first gear. When it didn't stall the idle would instead hunt up and down for a while before it would settle down normally. He finally got it sorted out and its about 95% right now. His biggest complaint has been the limitations of the gen III pcm compared to the newer ones.
They've (builder and tuner) have got a ridiculous amount of time in the tuning already so even though I haven't experienced any idle issues with the ac, I'm happy to provide him with this input.
