MAF in front of ProCharger question
MAF in front of ProCharger question Do you NEED to connect the bov into the system when running the MAF in front of the blower? My old setup, MAF after the blower, I had the bov just venting to the atmosphere. I was told the bov needs to vent back into the system as to regulate the air correctly for the MAF.
Any comments or suggestions with this?

The computer is depending on the notion that every bit of air going thru that MAF is going straight into the engine. The computer has no way to know that the surge valve (bov) is placed in between the throttle body and the MAF.
As such, the computer is going to think the engine is ingesting all that air you are bypassing and add the appropriate amount of fuel.
In short, the inlet tract between the throttle body and MAF CANNOT have any leaks or surge valves (bovs).

I'm used to understanding a MAF when it's in stock configuration. This is a new concept to understand with the MAF in front of the blower and comprehending how the air travels within the blower system. It's a learning curve like anything else.

BOV=Blow off valve, do you have yours venting to atmosphere?
