Oops, I remember now! lol my bad. For comparison on a 4.75" I made about 13psi (but my meter couldnt do decimals) at 7500 with cats. So I guess it's not too far off like you said with cam changes and sea level differences. The P1X is pretty impressive.LOL We pm'd in great detail about my car before I did it. P1X, 18 mani, mak deletes, and custom catback. Also why I was shocked to make 12 lbs. Lund must have some cam timing making boost a little higher than expected, but jr said it was right on what he expected.
