I have a 2000 Corvette and am putting a LS3 into it. Ill be using a LS3 blade style MAF and notice in the LS3 tune the scale starts at "0", ends at "15k", the LS1 tune file it starts at "1500" and ends at "12k". Is there a way to alter the scale so I can input stock LS3 values into my LS1 tune?

Are you using the exact stock intake setup from the LS3? If not, it isn't going to matter since the LS3 values will be incorrect.
youll have to tune it.Originally Posted by Ls1c5vette
tune the MAF
tune the VE
tune the timing
etc
Can't change it.

Not sure what this means. It doesn't take much of change at all for it to be a totally different calibration.
You can't change the axis of the graph. You'll have to dial in the airflow numbers to fix the GEN3 table. The numbers will be drastically different. It likely won't even run with the card style MAF on the GEN3 table.

I usually copy the best i can values from a file that matches the maf im using. Doesnt always directly cross but you can get it close.
I'm running a C6 card MAF in my C5, using a C6Z air intake setup. You can try copy/paste my MAF table and that should get you in the ballpark, enough to run it, and tune your tables from there.
