JB4 BEF

Whats the difference between the regular JB4 flash vs the pump gas BEF and the E85 BEF? I installed the pump gas BEF and it is a lot more linear than the torque bomb for the regular JB4 flash. Is there a difference for the pump gas BEF and the E85 BEF in terms of power delivery as well?

The various BEF files have ignition advance and fueling optimized for the specific fuel/use guides. Additonal information is posted in the BEF thread directly:
