This is strange...
Put a TS MS4 Cam/springs/PR in my 02 Z06. 239/242, .649/.609 111 LSA
Done the obvious idle air flow/ startup airflow corrections. It will idle sitting still but as soon as you let out the clutch past a certain point and try to move the car, it stalls. It is digital in nature, looses all power and is non recoverable even if you put the clutch in.
it feels as thought there is a switch that cuts fuel and spark.
