I'm glad you've got it all running.

When you fail emissions due to high NOx levels just remember where you threw those EGR components... Cali emissions SUCK!

Actually, these days most people who actually know how the system works do not recommend removing the EGR system... it's sole purpose is to reduce combustion chamber temps in low throttle conditions. It reduces NOx, reduces engine temp, reduces knock (yes, knock is always there), and keeping the chamber nice and cool may provide better responsiveness when you first mash the pedal. At WOT, the system is OFF... I understand why you pulled it, but for those who think they need to go out of their way to delete it so they'll get some big performance increase, they're quite simply wrong.
