    wont rev passed 5500 when warm

    car runs great for 10 minutes then it runs perfect up untill 5500ish then the power falls on its face recently replaced o2 plugs plug wires cap rotor fpr. i think its either my fuel pump or the ecu temp sensor or my dinan chip is screwed up the car pulls great on the down low and before it gets warm any suggestions would be apreciated o and i gave it a compression test which was perfect

      Check a couple of things.

      Air flow meter
      Crank sensor

      If you have your stock chip, put that back in and see if it makes a difference too.

          Check the operation of the WOT switch in the TPS. It sounds like yours isn't working.

            okay its kind of lacking in the mid range to but if its not on the WOT on the TPS the maps probly fucked which i think it is cause it only does this bs at WOT thanks any other ideas would be greatly appreciated
