Default Car Won't Run

Did heads/Cam fired up everything was good. Put it on the dyno, made a few pulls and then the car won't start and stay running. Even when you can get it to barely idle, you can pedal it but won't rev past 900. Even 1/2 throttle! It will not respond at all.
Changed cam sensor, tried a different maf, leakdown good, fuel pressure good, has a code but can't read it on HPT unless running... Autotap shows a code but won't tell you what it was... Its a 98 A4 car
Any ideas ?

Check your electrical connections. Maybe one of your injector harnesses came unplugged...

Could programming cause a problem, maybe it screwed the ecm ? Although it has been reflashed and still does the same thing. Not sure if something internally could have shorted or something...
