As noted, P0420 and P0430 are cat codes. You should have all cat related codes turned off, as well as cat protection. You should also have all secondary O2 sensor codes turned off. Looking at your numbers, you went from 379 HP stock to 427 with your mods on E60. 48 HP is a respectable gain. Don't get to hung up on numbers. Like it's been said a thousand times, different dynos read differently. If your car rips, enjoy it!
