One point regarding engine control and coolant temps. I believe Pete runs his calibration in Open Loop. The ECM goes Closed Loop ~ 64C, but it does not update the BLMs until CTS reaches 80C or 180F. So if your chip is programmed for Closed Loop, it will not update fueling as you drive because it does not "Learn" at temps under 80C.
