I have been out of town, but our last "test and tune" was last Friday. If I had went there after work, the DA would have been 2860 (Famoso raceway, May 29). A 12.70 sec @ 107 mph car at a DA of 2860 corrects to 13.25 sec @ 105 mph.

The seat of the pants dyno tells me the same thing. My vette ran a 12.8, but is way faster than my 370.

To be honest, my car was "bogging" from 5,000-7,000 rpm. I thought it might be from detonation (and subsequent timing retard) because the weather was almost 100 degrees and my timing is advanced over stock. So, on an empty tank I put 5 gallons of 100 octane unleaded in it and dynoed it. The breeze was running the wrong way through the shop, helping to heat soak and keep intake air temps sky high. The ambient temp was already 98 degrees. The runs were on a dynojet. The best run? 290hp. :-( with intake, exhaust, cats, headers, remapped ecu and race gas... Only 290hp. There's just no way I'm going to get into the 12's on the track where I live.
