dragonmaster093,
You could be right. I'm still tuning and will never stop.
I feel this is due to the restrictive airflow path. On my EFI Mustang, airflow is channeled first thru a 90 degree elbow, throttle body, another 90 degree elbow, MAP, straight 4" pipe, another elbow to the fenderwell. It's like sucking air through a crazy straw! cheesy
or
a carb.
