Fuel pressure is right on the money.

2nd tank of gas dropped to 16.xx-mostly city driving.

3rd tank is back up to 18.3-half highway and half windy mountain roads.

I guess I'm done. It still pings too much some times but I can't find anything wrong. I'll stick with 89 octane and plugs 1 step colder-that seems to be the best mix.

I'd love to have one more pull on the dyno just for grins but $ prohibits that.

Thanks for all of the help.
