Mike T Dyno question
You have said here in the past it may take a while and a few miles for a 1715 tuner to take its full effect. If one were to dyno, while having it installed for a period of time, then remove the programming, (would you need to reset the computer by disconnecting the battery?), does it return to stock right away?
Thanks JA

Hi jstang,
Good to see you again!
Flashing the PCM with the Micro Tuner (either to upload one of the performance tunes or to revert back to stock) wipes out all the previous changes made by adaptive strategy, and you begin those "adjustments/adaptation" process again from scratch.
After running the performance tune, revert back to stock with the Micro Tuner, and then start the vehicle to make sure all is OK - then at that point, you can clear the PCM by disconnecting the battery, insert ignition key & turn ignition to the "ON" position for about 10-15 seconds, and then turn the ignition back off and REMOVE THEY KEY from the ignition. Then re-connect the battery, and you're set, back to stock. There shouldn't be any significant delay in getting back to stock power levels, assuming we're back to 87 octane in the tank - higher octane on the stock program can actually reduce power in some cases (as well as slightly raise it in a best-case scenario), so you'll want to be back on 87 octane for comparison.
There are some who argue that it's not necessary to clear the PCM after returning to stock with the Micro Tuner, because the process of flashing the PCM clears out the adaptive strategy adjustments - me personally, I just still prefer to clear the PCM after the flash - call me old fashioned.
The issue of the PCM needing some time (in terms of both miles and drive cycles) to adapt to the new programming is most applicable when changing *to* a performance tune and getting the most power gain from that new tune, as opposed to changing back to stock - though I like to clear the PCM either way.
Take care & hope you enjoy your holidays!
