Every dyno chart of a 13b 6 port I see builds power very quickly. Mine is terribly slow.
I attached a comparison of other dynos and mine - called mikes itbs.

I have a 85 13b 6 port with twm 50mm itbs on the RB manifold with the long primary exhaust. Its ported within the limits of my class, street prepared, but its essentially a stockport. Everything is balanced port matched bleh bleh bleh. Im using 2nd gen ignition and a haltech to control it all. Should be a pretty sweet setup.

Any thoughts?
