hi guys, need ur advice...recently i've change the airfilter from open to box, new header and new piping from 2 inch to 2.3 inch...so the question is, do i need to retune my emanage coz the car feels heavy....

Probably need to adjust your fuelling a little as your most likely running a little leaner now due to freeing up your exhaust flow

oic....FYI, the previous owner have this kind of piping size....collector 2.5, center 2.3 and at back is 2.0. is that insane or what.....i dont know why he done that....

when i change new 2.3 all the way,no wonder it feels power at the end but less power at low...i think by tuning it settle's it...i hope....
