How rich is too rich?
I finally got my LT4 to the dyno today and the WB showed it to be rich. Very rich. As in 11.5 or thereabouts. I can scan in the graph it it'll help.

Re: How rich is too rich? (Darkness)
Looking at the dyno graph it shows it as being at 11.5 to 11.8 It never gets over 12. There is one dip at about 2900rpms where it goes down to 10.9 and the hp and trq suffers as a result. I didnt have any software hooked up to check for spark knocks or timing retard.
It doesnt sound as if it's running too rich, but maybe there are a few HP there to be had with some good tuning. I will most likely wait for a custom tune till I get some other, more serious mods done and go from there.
