I just wanted to run this by you guys ,
usually a code 13 pressure sensor will cause a limp mode right?

well ever since i installed my FEED tune Hks Fcon V ( ~ 5000k`ms ago )


i always get a resident code 13 .. if i take the piggyback off no code 13

the car runs well .. i boost 12-13 psi regularly but it`s simply puzzling the code 13 issue ..

also .. prior to using the HKS i was using a pettit Unlimited .. and no code 13

any thoughts ?

thx
