EGR: Exhaust Gas Recirculation, basicly the ECU dumps out exhaust gases into the inlet to lean out the air/fuel mixture and burn off some of the unburnt fuel (hydrocarbons). Not sure there would be a niceable difference in running except for perhaps an increase in response.

Lol my head exploded looking at the ECC system flow diagram in the haynes manual!

also heres the link to the guide;

this removes all the EGR (exhaust gas recirc) system.

dont remove the ECC system or any of the rest of it, you have the ability to have your ECU remapped and having the ecc means you have a mass of tuning potential available including fitting turbo's and the such

removing the EGR will easily free up a fair amount of power (take the CAT out also, which you will when you replace the exhaust system)

Thats what i got in a PM from speedle when i was contemplating completely removing the ECC... Hope it helps!
