id say this has been posted before but i couldnt find it ,basically im going to get my 98 type-r impreza mapped soon as i bought a FMIC and another fieu bits n pieces ...but i want to do as much as i can with my car (low budget) before the map that will give me an advantage ........a fieu lads said to me i should remove the air-con (pump/pipes/rad ect) ....is this a mod worth doing?
