I am following directions from my purchased Dodge tuners course and they are building tables from a Hellcat that has a lower stoich than mine to build tables. There’s, (0.0688), mine, (0.0720). My tables for spark retard are looking to be higher numbers than theirs. My car was tuned with a supercharger and I am tuning for my add ons. Long tube headers and no cats. Should I back up and start with their stoich.

I'm sorry but at this stage we don't offer support for the Dodge platform and I'm not sure what course you're following to build tables from? If you've got an existing tune for a supercharger then the process of optimising this tune to suit long tube headers and cat removal should be relatively minor though.
