I took the car to get dynoed when it was 100% stock and then took it back after the cats were installed. Nothing else was changed, I hadn't even gotten gas in between dynos. Not a whole lot of ways to fudge numbers. It's not even my dyno, its an independent shop that works solely on modern American muscle cars so I see no reason to fudge numbers. The numbers I posted are the numbers that make up the difference between MY baseline dyno and MY dyno after the HFCs. Hopefully as people order them, we will get some more independent dynos.
