This is exactly what I needed! I read this a few times and got a weird idea to do a reset from the beginning. Turns out it must have been a bad initial tune where the computer learned some bad habits and stuck with them since I didn't turn off timing control on first startup but only later on. I ended up turning off closed loop on the handheld, reloaded the initial wizard and started it up. Adjusted the idle screws a little bit and got it around 750 with the IAC around 2-3%. Turned closed loop back on, went through the different gears and revved a little and it always went back to where it should be. Thank you so much for your suggestions, I would've never thought about this even being a possibility!
