Engatawork,

Thanks for the C-clamp idea. I actually thought of that the other night but was too darn lazy to go down in the basement and dig out the clamp...then I got frustrated and gave up!

I got a big boost in power (of course) when I cleaned the bolt and banjo fitting on the intake... then put the boost gauge on and found I was only getting 8 pounds, max. Restricted the hose as a test by dialing in a needle nose vicegrip on it to get 14 psi at max load. Drove like a completely different car. Much better performance off the line and up to highway speeds.

...The second big hit came when I turned the ALDA screw CCW 1/4 turn. 1/8 turn didn't change anything, but 1/4 turn and yahoo!

Thanks for the comments and the link, everyone. I'll try to track mpg for the record but it's tough because I switch back and forth between diesel and veg oil (heated tank in the trunk).

And by the way..with boost and ALDA adjustments 100mph comes right up with no fuss. Not bad for 18 years and 384,000 miles!
