You should have so much boost with a stock pulley and no cat. Something isn't adding up.

My pulley is not stock it'* a 2.3. Will a scan tool do anything without the CEL being on??

He said that his boost guage read 10+ before and after. If you remember, on my '93, it always did that, too, the guage wasn't reading right. It was either in the cluster, or at the SC. I had to usually guess at my actual boost.

And I had a 2.2" pulley. The guage shouldn't read 10+ all the time. My guage was broke.

I have a strong feeling this is going on here, too, so we can't trust that guage for nothing.

Sorry, brain fart on stock pulley size...

Is it always above 10 or just at full throttle?

I think it'* time for a scantool.

Just at WOT. It feels like a turbo now it kicks in rather the smooth power all the way up the RPM range.

Check over the positioning of the boost actuator for binding of the rod that controls the bypass.

At idle, disconnect the top vacuum fitting on the actuator. The bypass should move fully and immediately. After that, spray carb cleaner on each vacuum fitting one at a time. Your idle will change if you find a vacuum leak.

Actuator works right. No leaks that I could find.

Get a scantool.
