Step 8: Test drive

I would start with the setting at zero and take it for a spin.  Let the engine warm up and let the ecu run its cycles. (since you disconnected the battery thus resetting the ecu).  Now test it on the freeway turn the ECT off and the OD on if you have an auto and try to make it ping.  Mine would ping going 65-75 MPG and applying enough throttle so the tranny won’t down shift.  If you have a boost gauge you will notice that it will head toward 6 psi.  If it is pinging then pull over and adjust the TMC 1.1 control knob.  Mine is set just a hair above zero, so you will only need to do a little adjusting at a time.
