air fuel setting
 

I have a 347 with a vortech t trim #42 injectors 80mm pro m mass air and fmu with t rex pump. trans is a built c4 w 3500 stall converter and manual valvebody. when I get to 6 grand the motor seems to sputter. I'm not sure if enough fuel is being pumped in. Would an adjustable pressure regulater help. If so do I adjust up or down on the pressure? I want to solve this problem before going to the track. The setup before the c4 was a lentech aod and yielded 11.3. I should be in the 10's with the new tranny if the damn fuel gets to the motor. Thanks 4 your help.
