    You will need to scale the VE and IFR tables so that you see dyn cyl air values lowered. Try 30%.

    i have dynamics injectors with the right configuration of it , and i return back in MAF tune so what you think i have to do with these IFR values..??

    It probably won't run right with the MAF enabled in a 2 bar COS. Either way, to fix the REP you need to scale the IFR and the VE/MAF by the same percent. Start by reducing them all by 30%. That should fix it.

    what code is it setting? Reduced engine power can come on for a lot of different reasons.
