My bolt-on modified Gen1 Viper has been on the dyno a few times now. The engine has
always run lean but the A/F was steady. Now that I've bolted on some underdrive pulleys
the A/F is leaner and more erratic - touching +16:1 at several points. What did I do
wrong. How can I bring things back to 12.5:1 A/F?
