The quick & easy way to tune your vehicle is w/a wideband O2 meter.
I use the LM1 from Innovate
http://www.innovatemotorsports.com/products/lm1.php It's about $350. but worth every penny.
You can use it on other cars, like your friends,or other people & charge them to tune their A/F mixture? So you can get your money back???
Just a thought???
