mfanatic- I have a before dyno stock and with headers. So we will be able to do a 3 way overlay once I get AA dyno'd.
Each handheld tuner I've used on 4 different vehicles cycles the cars electronics, including the ESS unit (which coincidentally looks exactly the same as the AA unit). Clicking, dash lights flashing, fuel pump whirring etc is all part of the experience. That's why it's very important to be on a trickle charger during the process. You don't want your battery dying in the middle of things.

Looking forward to your results
