A day of countless hours tuning on the laptop finally yielded some semblance of a baseline. The issue is a combination of suspension and apparently a massive amount of torque. Ihad it blow the tires off but go down the track, hook but not run, spin AND not run... So I threw a Hail Mary at it for first round, combining the fuel and spark maps from the run that it hooked, and the other half from the run it went down the track, along with some very small tweaks. Hooked AND went down the track... And much to my surprise even got a W. Feeling much better now. Car works somewhat, and got both cars in for Rnd 2 tomorrow!
Oh, the in-car pic in the previous post is to illustrate "Real Stockers Have Cup Holders.".
