Another vote for a custom tune.

 

Nelson all the way.

 

So far, there are NO BETTER spark plugs than copper ones. If you are NA, get some ngk tr5 plugs. They should only last about 10-20k but they are less than 2 bucks each and will outperform all those "good" plugs, as far as spark energy goes. I wouldn't replace the wires until you need new ones (50k or misfiring).
