Your AF ratio, seems a tad high....I get nervous at 12.0 : 1 plus a couple tenths. I have been told optimum wot for my blown motor is 11.5:1 plus or minus a couple tenths... i'm sure some one will correct me... 14:1 on closed loop or a bit higher is common, but not on wot dyno runs....with nitrous, I would be verry nervous if that was over 12 while spraying, but hey, some people will regard it as job security, if they are building custom engines

that second run the TC unlocked... get a real dyno tune with the TC locked and the tranny commanded to stay in 3rd gear. feathering in the throttle in 3rd gear wont get an accurate reading either.

My bad, I saw the giant torque spike and thought something was wrong... however it's still important to amke sure the run was TC locked/3rd gear, because otherwise all the numbers will be all out in left field. Can you verify this was done?
