The fact that your transmission is operating correctly is a good sign that your vacuum system is setup properly.

Just a mild correction. The line going to the ALDA is boost pressure, not vacuum. If you want to operate the engine without the ALDA simply disconnect the tube. My understanding is that this will cause it to act more like a normally aspirated engine as far as the amount of fuel delivered is concerned. The tube is not very flexible, so don't try to clamp it closed.
