I have a licensed pcm for a 2000 Chevy Silverado 5.3 in a tube chassis rock crawler. I have been very happy with HPT and the ability to modify the tune after cam changes and other mods. I am now building another tube chassis and have a 2001 Chevy Silverado 5.3 to put in it. What I want to do is flash my exact tune to the new pcm. I have searched quite a bit and found conflicting info. What is the most efficient way to do this? I know I will have to use 2 credits for the new pcm. I have also read that I should do a "Read Entire" on the new pcm and open my tune file as a "Compare File". Then, copy and paste everything from my tune file into the new pcm file, then do a "Write Calibration". This seems really time consuming and opens the door for a copy-paste error. It seems there should be a quicker, more efficient way to do this. Any help?
