I wonder why one would bother with the vacuum lines and vacuum reservoir required to get a stable vacuum to measure. Alph-N works great all on its own with ITBs.
I am sure that there are a variety of pedals you could use. I think that a lot of people use BMW street car DBW pedals for this.
Here is what I did:

Scott,
Are you also using the TPS to control ignition advance and if not, how are you controlling it?
Thanks,
