reduce engine power Help !!!
O.K guys I tried to take the car to the dyno yesterday but when I started the car I got the reduce engine power thing... 
The weird thing is that as soon the engine light comes on the fuel/oil/temp gauges goes to zero and the car almost dies my tuner still didnt check the car But any heads up will be appeciated...
Also any dyno numbers guess pump gas 13-14psi for now. !!!
Thanks in advance.

If it's happening from simply starting your car, you're most likely out of bounds on your P0121 table. Raise the max and lower the min values. Set the max at 85kPa and min at 35kPa. Go to Engine Diag>General> TPS sensor.
You could also be out of bounds on the P0106 table, located in Engine Diag> Airflow> MAP sensor. Raise the max and lower the min in those tables too.
