Your best bet is to contact James at shortuning.com. It'll cost a little but if you give him all the specs on the car, it won't be on the dyno long. He's awesome with the 24x.

I appreciate the feedback! It is showing 90 on KPA and just keeps falling on its face at 1300RPMS and wanting to backfire. I changed out the MAP sensor today and same result, will circle back on stuff...

I can email you mine if you want. It's WAY better than the 24x tune in hptuner's repository but I'm still experimenting with some fueling aspects. Have you entered the correct data for those 42# injectors? That should have been step 1.
If you're seeing 90kpa with a new map sensor, then that's really weird. If loading up a new tune file doesn't help, then I'm not sure where to look in the hardware. Maybe you have an enormous vacuum leak somewhere?
I think that should also help with the question in your other thread. Try a new tune file, and look for a vacuum leak since 90kpa is pretty much zero vacuum.
