    7A dyno run / lambda values?

    I'm sure you guys will find these figures rather amusing

    Power is fine but i'm down on torque, i got 207nm which is 153lb/ft. Can somebody look at the results and tell me what you think, the lambda value seems to drop way down after 4000rpms. Should i start looking into fuel pressure and regulator or do i just need a remap?

    Thanks,

    Mark.

      Yes the stock Hitachi crap, they were cleaned and flow tested about 5000 miles ago and performed ok then. Would bad injectors show up like this?

      Engine runs smooth, idles fine, and emisions were fine too at .65% co. Its just such a suddon drop at 4k seems strage, and again at 4.5k rpms.

      Cant get my head around how it can produce stock power but be down on torque
