He doesn't work like that. He never uses a "generic map". Yes, I'm sure mine would be somewhere near, however someone else might have better compression, and be able to take a bit more fuel / not be lean, my cams might be worn - not giving as much lift, maybe my exhaust flows better, maybe someone else will have better venturi trumpets etc etc.
From what I can gather, Wayne maps every car - correctly.
