I changed the pulley out on my car. It was pulling hard through 6000 with the old pulley.
I installed the UD pulley (it charges great with the new alternator even at idle!).
I push in the clutch and it swings through 6000 RPM smooth, however under a load, it falls on its face (bogs down) 5500-6000 and bogs for 1 second after the 1-2 shift. What the crap?

Any input would be greatly appreciated!

It might be unbalanced enough to be kicking the
knock sensors and giving you knock retard. Only
way to tell is to scan it and catch the action.
