Agreed. I made the switch also awhile back, and will be staying with the 8E's.

We sell the pulleys by size, rather than pressure, as that depends on a number of variables. We include pressure estimates. If we get enough feedback from customers suggesting otherwise, we will adjust. I think one or two pullies were changed based on customer's suggestions.

Interesting and surprising. I always felt the original specs were right on the money. I'm at sea level with pretty standard TP/cat back exhaust mods and have confirmed these specs on my own so far/
