Gazi.....that last one is pretty much the same as that messy hand drawn job I posted. I much simpler. I believe this originated from DaveH. It does work and was the most helpful, for me.

guys this may sound dum but that is the vpc andwhat does it do, thanks

 

lilnard.....The VPC is designed to physically and electronically replace OE air metering devices which present a significant restriction to the intake system and offer no adjustment or reprogramming options to take advantage of dramatically higher air flow or larger fuel injectors. The VPC converts both air flow meter and air mass sensor systems to what is referred to as speed density systems by utilizing a 16 bit central processing unit reading its own intake air temperature sensor and absolute pressure transducer (B-MAP sensor) signals.

This unique conversion feature allows the VPC to completely replace the factory air flow metering device. Another benefit of the VPC is the ability to create your own programs to take advantage of larger fuel injectors and larger turbos.
