the +16 fuel trims almost lead exclusively to some type of leak somewhere. Fuel trims should not be that far out of line normally.
If you open up the PE Time vs RPM table, you'll see the very first window in seconds is 0.0. From 400rpm down to 4400 RPM (or so) increase the fuel there by 5-8%. That dumps fuel immediately, and then it will clean out across the PE table, just don't touch anything else in the tables. It looked odd to me at first, but it's a trick I'll remember from now on.
Did you ever get your Alky figured out?
