The stock 93 performace tune did better than my 87 custom performance tune...

You can run 93 and add about 2-3 degrees of timing to it. But start with 1.5 advancement. If you dont have trouble go to 2 then 2.5,2.75 but I would advise against going over 3. When you are adjusting the timing you will raise it and get a tiny bit more power, when you dont have any increase in power or the engine knocks then take it down a bit. You do not want to have too much timing advancement because that is really bad for the engine.
Funny, my custom 87 on 87 beats my canned 93 on 93.
