Thanks to Russ K I updated my IFR and VE tables to what is "believed" to be the correct data. The car will idle in park but as soon as you put it in gear the car stalls out. It only happens with the new injector and VE data. I'm a little lost and just reaching out for some different view points.
Try this tune. For some reason the STIT in gear were stuck at 1.6 g/sec. I think that was because the throttle follower delay in gear changes you made.
And use my idle .cfg file to scan. You want to use less than 24 bytes when scanning to improve the frames/sec.
