Is it OK to put a CDC3 calibration/tune on a CDC2 PCM?

I was told it was OK but I'd like a few more opinions.

Got one on mine, 1/4 mile times are good enough for my liking as well as we just changed all of the plugs after 12,500 miles and over 50 passes on nitrous. Not even one plug showed detonation or even too rich of a fuel condition. KenB at Modular Depot was the first one to let me know this was a possibility (running the CDC3 tune) as it has some updates that cures some nominal issues from previous computer codes.

That's right, I always use the latest value file available because its like updating the PCM from Ford already. CDC2-CDC3 and BKT2-BKT3.


Thanks, Doug.
