I have a supercharged miata that just go out of the shop. First we changed the plugs, then the egr valve then the fpr vave and the fuel filter. Then changed the injectors. Cut the cat to see if that was faulty and still have barley any power. The car will run but when cas is appied it feels that no power is there. It will accelorate but very slowley and will stop at about 3000 rpm. I can not figure out what it could be. The car is boosting so the supercharger is not faulty. There just is a HUGE lack of power. I get zero to 60 in about 20 seconds. PLEASE HELP

Jmwagner1 and all Miata mechanics ---
Just replaced my mass airflow sensor with little or no improvement. I hope your fix works. Timing, vacuum leaks, oxygen sensor, fuel pressure 40-44psi, new fuel filter, external timing belt, new spark plugs and wires all checked out perfect, replaced mass airflow sensor, no improvement. Still surges on takeoff and pulsates until 2500-3000rpm, then seems to run as though a supercharger kicked in, though I do not have one. Injector specialist said they are perfect. At this point the last suggestion was to replace the throttle position sensor which I have not yet done. Any and all suggestions welcome to help my gutless wonder once again perform as a normal automobile. Reply to Alex or Harmonical@comcast. Net
