Guess how many hours it takes to make a stock 5.7L 4L60E $0D bin file into a 7.4L $0D bin file?

Almost 5 hours!

The worst part was I had done this before and lost the file in the computer crash of 2012...

But I think I have an issue? This was a stock BJLH 1994 5.7L vehicle to 1988 7.4L engine which I think both use same EGR control? I used a $0E 7.4L bin for all the parameters including EGR and was surprised at all the differences there... then it came to me that... I think the 1994 7.4L uses a Linear EGR and the 5.7L does not? If someone can clarify I may have to change all the EGR parameters back...
