So now, with this information, I'll be starting a new project on the intake side of my S/C.
I'm going to move the MAF to the pressure side of the system, just ahead of the intake manifold. This will eliminate the MAF as a restriction, I'm sure it flows more than enough air to be on the pressure side.
Next will be a custom throttle-to-filter tube, eliminating the Whipple one.
And then the biggest cone-shaped K&N type filter I can get into the spot formerly occupied by the stock airbox.
I can't wait, it was so exciting to find why the boost was dropping off, and there is probably a lot more free (almost free) power available.
