Why is it so hard to get good advice !!???

The distributor is a MP electronic with vac advance. I have it plugged. I have the chrome ECU and the plugs, plug wires, cap and rotor are all new.
Timing curve of any kind, it should have run detonation free at 30 degrees if it wasn't running lean, right? The exhaust smells as clean or cleaner than my 2007 truck. NO smoke, almost no fumes of any kind.
