Hey guys,

I'm stumped. My Whipple was making around 10lbs of boost and peaking at 12. Now I'm only seeing 5 or 6 max. I have replaced the belt and installed a new, pinned ATI crank pully. Per Whipple, we tied the by-pass open and as expected, no boost. Tied it closed and only made 5. No vacume leaks that we can find and no idle problems. We will be pulling the intake this weekend to check for cracks or bad gaskets. Anyone have any other ideas?

Thanks,
Scott
