I didnt use any of that MSD BTM. Your timing is advance about 7 degrees at about 8-10 psi boost on the "hack". It's not really that bad. I kept my on stock timing. What others have done is retard the intitial timing to -3 to combat that problem. But dyno hp did not even make too much of a different and the A/F only made minor improvements.
For ease of mind, you can get a 6 BTM if you want. THis is my PVC set-up... basicaly like stock:
Intake section:
Filter-----Tap 1------ Tap 2------ compressor
Tap 1 is the tubing that leads to the PCV hose and valve cover breather.
Tap 2 is where I put the IAT sensor
Caution:
Do not use the MAP check valve or the Missing Link for the hack set-up. It will mess up your setting and timing even worst. Allowing the MAP to be bypassed will send a false output from the AFC to the ECU therefore fuel calculation will be terrible....
