I am being a bad boy today and farking off at work. It's a nice day, so I brought the car to tweek it a bit.

I believe I have the secondary spring issue worked out and the car pulled as strong as it ever has down the industrial street I work on... with the air cleaner off.

As soon as I put it on, the car goes back to it's sluggish ways. I checked the air horn vacuum flap and it operates smoothly. However, I think I am still pulling enough vacuum during initial acceleration to prevent the flap from opening and starving the car for air.

The current line on the air horn attached directly to the manifold port. About 22 lbs at idle.

Any thoughts?
