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.
