Sure do, Most have similar results. For instance stock CTSV out here pulls no better than a 13.2 which is great because i beat a stock CTSV in my grey car at the moment. New SS camaro runs 14.5's. ZR1 stock doing 12.1 's.

So intereting that when I put custom manifolds on by time increased and even after I got the suggested tune. Then going back to stock manifold I still cant beat the 13.5 when I was doing 12.9-13.0 on the same set up.
Car still runs strong though. Does a 178mm pulley ever stop giving power? Ive ran it for about 40,000 miles now almosst 70,000 total on blue car. 50,000 on the other.
