DECADES DYNO3VASPEED

Dyno runs performed at Virginia Speed in Virginia Beach, VA: Run 4 was on 9/7/2013, Run 8 was done on 11/22/2013. Same before/after info as on the 1ABACUS picture. The A/F ratio of the after run was rich like Run 8 at Abacus, not sure if this happens once it gets warmed up or if it is a problem. All 3 (1ABACUS, 2ABACUS, and 1VASPEED) all SAE corrected w/ smoothing on 5 for apples-to-apples comparisons. I'm not sure why the "after" numbers at the two different placers were so different; I'd like to think that the higher numbers are the correct values, but I don't have any reason to suspect one is more accurate than the other. All dyno runs were done with Shell high octane (93?)- the "after" runs were both done on the same tank, so that shouldn't be the reason.
