I guess that means I'll have to blow 2 more credits to tune the 03GTP pcm, currently just have the gt license (not the entire year). Does it make sense to try just a Write Calibration and see if that works, before attempting a full write (read a few horror stories of people screwing up pcms after doing full writes).
Ya, HPT credits...what else you gonna do with them? Have you read the OK tuned pcm and saved it?

I don't know if you need to update the VIN in the OK pcm. If it sets off a security code/lite or the radio and things don't work, then I guess so. I would try running it with the OK tuned pcm as is. The GT trans is 3.29 geared like your old setup. Not sure if the valve body difference deal matters in this swap. What about test-running it on jackstands?
