Hey Eric, thanks for all your help first of all. You are helping to make these add-ons a lot of fun. I have a few things to note and some questions about my 84 hot-air set-up. 1- Am I able to do any tuning in the tune window of the PL with the Axis chip? 2- I adjusted the TPS using the SM-G, to the recommended settings .42-.46, now the car wants to stay in gear when slowing down which causes some stumbling nearly stalling. should I bring the setting up a bit? I adjusted the shift cable but noticed it a couple more times after that. It doesn't seem to know what gear to in sometimes. 3-It seems to run a bit rough and kind of stumbles a bit on acceleration. I'm still learning to tune, making only one or two adjustments at a time. 4- how long of a drive should I take it on between adjustments?
