We are doing an L99/6L80E transplant into a 53' Chevy 5 window and it is going to be a family members first vehicle.

Needless to say, I am looking for a best practice to derate this thing for a while. So far I did not see an obvious pedal map in my brief digs. I was mostly reading the VATS threads and looking at that aspect. If someone has an idea for how to accomplish this I am all ears. Otherwise I'll play with some options here soon after it is running. Current status is routing the fuel lines and hanging the wire harness.
