First of all, im new to the forum, picked up my Zed sunday
2004 GT UK model
This question has probably been asked before, but im under the impression that fitting these items (Cone filter, Y-pipe cat back) will make the car run LEAN, requiring a remap.
Or does the car sense its running lean when you fit the items and adjust the fuel accordingly (i thought this was the idea of an o2 or MAF sensor )
Thanks for any advice.
