So, I have the PC5 w/ AT-300 installed, had a dyno tune done to get me close and when I have AT enabled, something very strange is happening around thew 2000-2500 rpm range - its as if its stumbling to run in that range. Before 2000 and after about 2400 or so is fine, any suggestions? What I've done as I thought to be the correct steps to be was to enable AT, ride about 20 miles, accept trims, save them, and repeat only to have that 2000-2500 rpm still mess up. I've ended up reloading the original map from the dyno tune and turning off AT and no problems. Thanks for any help!
