Factory cats, but I think I know what happened.
I bet the base line run didn't reflect giving the ECU enough time to adjust to the K&N filters (takes 3-5 runs for the ECU to adjust), which he claims to have also had installed in both runs.
So... my guess is that the baseline should be interpreted as "without K&N's" (even tho' they were installed) and the second run should be interpreted as "K&N filters + CBE" -- that is a more likely explantion for that big gain in power.
