I went for a drive with the EGR vacume hose disconnected, and wow it pulls so much harder. The vacume hose is enough to keep the valve closed all the time? I was expecting codes, but i didnt get any either. Had some fun with 2 civics on the highway. Is the EGR something u can get power from? or is it very little? Id think so considering it lets already burnt exhaust gases back to be reburnt, more oxygen would create more power. I noticed my cat got really hot though, i knew this because even after i connected it back, and drove home easy to let the engine coolant and oil cool down, and let it idle at home, when i turned it off i could hear the cat contracting hard. Would a higher flow cat help? or i might just take it out completely.
Anyone runnning no EGR or blocked it off?

The EGR system on cars is only activated at part throttle positions when you go to WOT manifold vacum drops to zero and the valve closes, if you got a power increas it may be that the EGR solenoid is leaking vacum to it at idle etc or the pintle doesnt seal properly, EGR delets have been sround fer a while since the first emissions equipment appeared on cars.
BTW speedy did you get the full video of the 442? I think i sent it but i cant remember!?! if ya didnt let me know and i can resend it.
