another case of the ~20 missing hp?
your NOT loosing that much hp through a properly functioning cat.
i've dyno tested open header vs through oem cat and 3" catback exhaust on an N1 equipped VE and lost very little hp.
post up a picture of the distributor position. if thats fine (near middle) then check the cam install.
of course, maybe its the dyno.
