all else being equal....then the short answer
is, the s/c pulley is spinning slower then
it was before.

could be, but if it is, that
would mean it's slipping more
now, then before (if any)

no its not slipping i can guarantee that the belt is 10 times tighter then with the stock tensioner
i just ordered the 12 pound pulley then i should be back up to 10 11 pounds

hey fade if you wouldn't mind, i'd
like to know if you can feel the difference
(really), between the 10 and 12 # pulleys.

if you come back and say you can, i may go
ahead and get it also......

Has anyone else noticed this? I want to get the thumprr tensioner, but not if I loose boost.

I might go with the frankentensioner if it doesnt have this problem.
