It is very important that anyone who loads in a new calibration file, fuel pump, MAF Sensor or throttle body (no matter what TB) resets the "keep alive memory".. especially but not limitted to the 2010 -2011's
resetting "KAM" in these cars means first disconnecting the negative battery cable then turn on the head light switch. Do this for at least 20 minutes with the head lights turned on
(head lights on because the power that is stored in the PCM goes to the head lights)
Then turn head lights off after 20 minutes and reconnect negative cable. start car, do not touch gas pedal or turn steering wheel and make sure the A/C and heat is off and let the car idle for at least 2 minutes.. an erratic idle is not abnormal when doing this procedure seeing as how the car is searching for an idle.
After the car learns its idle it should be fine moving forward. Then you can/should turn on the AC for a min for the computer to adjust to that change and into gear (if automatic) Then take it out for normal average driving to complete the process and allow the proper time for the computer to go through it's adaptation (usually 50 or so miles)
