Do you have proper gages to test control-pressure and vacuum?

If not, it would be a worthy investment.

When you do your dyno tune, have them put there wide band in place of your O2. Also, unplug your O2 so the Lambda-computer will not give you funky AFR's.

This is preferred to sticking a probe up your tail pipe. On the dyno you can set your O2 a little fat if you like and if you do not go to far, when you plug back in the O2 it will bring you back on idle and cruse.

You might even un plug your O2 now as a test to see if it changes anything. It should not unless the throttle switch is not functioning correctly. Many just run without the O2 plugged in.

The best.
