hi ppl at the moment i have a 02 wrx with a full stainles from the turbo back and matching uppipe with the standard td04 turbo fitted . the car has been mapped already not sure on what type of map but it pulls a nice 1.1bar of boost in the higher gears and has no ecl light coming on . if i was to fit a vf 28 on to the car would i have to get it mapped straight away are would i still be ok driving it round and still using boost m. thanks kev

 

Yes mate as the volume of air created by the vf 28 is alot more than the TD04,your motor would be detting its *** off if you didn't,and motor rebuilds are alot more than a remap.

 

yep defo remap
