Every time my car gors for rr sumit is wrong! so onto the new problem.

ive heard about mapping out the maf mine has gone down hence why it aint producing what it should so my next question is do i just replace this or get it mapped out? If it is mapped out what are the gains/benefits if any over running a maf based map

depends on the year --if it's EDC15 you can do the diode trick if 16 I think it needs doing by mapping

Care to enlighten me its a 54 plate if that helps

up to approx. '04 then I think it's a remap job

Simple enough to switch to MAP sensor based smoke map. Some BLT's are setup this way.

No power gain benefits.
