Big problem with my power dyno numbers

You want to mount your boost refrence line for the fuel reg in the carb hat. If you mount it below the throttle blades it will see vaccum and lower your fuel pressure. This is how the guys set them up at turbomustangs.com. Do you have a msd btm? You want to retard timing with boost 1 deg to 1 psi. Or you can lock it out.
