Hey Gang!

I am about to stuff the 2056 back into my car and I wanted to double check a few things before I dive head long into this thing.

My A123 has a vacuum port on the side of the distributor body. The GoWesty throttle body also has the vacuum port. I assume I connect the TB to the A123 ports and I'm good to go. I ask because there are lots of comments about 'if the port is before / after the throttle blade. The port appears to be in the same approximate location as the stock 1.8 TB, so I think this is correct.

Second question, with the 2056 and the Raby "FI compatible" cam, the rest is stock L-Jet FI (I moved the TPS over to the GWTB) -- which of the pre-programmed advance curves should I be selecting in the A123?

Thank you!
Ted
