EGR has nothing to do with the power difference between the C16 and X16XE's as it shuts off at WOT anyways.

It only works during in light throttle anyways. It only really draws exhaust gas out of port 4, so isn't massively effective anyways. Blanking it off it easy enough, but simpley unplugging it produces fualt codes. blank it, clean it and it won't get dirty and won't cause issues.

Power on the C16 can be down to
inlet port design
CR
cam
management system.

the above is correct it adds more air to the emissions to dilute em

I thought it just pumped in air to dilute the emsissions in to looking better, sneaky cheat:lol:

It's extra weight to be carrying, and excess weight is worth loosing.:)

Does taking off the egr pump thats infront of the battery on a 1.6 sport make any difference. If so then what do you have to remove and block etc...
