Sorry that I have not got back before this. I am now out of work, things have been tough.
Sebring is a good shop. I bought an oil filter there for my spider a few years ago on a Sat. The older gent(late 60s) behind the counter said that he used to work on Alfas back in the 70s. He knew all about the Spica system, in fact also knew Wes Ingrim back when he had a auto repair shop in Madera. He said that he had all the Spica repair tools as well. I did not get his name and when I went back a few months later for some spark plugs, he was not there and no one knew who I was talking about when I asked about him. Darn
140-150 is ok.
When you're getting down to 120, then it's getting pretty weak. What's also important is how the compression builds. You should get 2-3 very good boosts at first, then more slow building to the top.
