Yeah it kinda does make me nervious lol. How would I go about correcting that? just lookup in the ems and add fuel at that load at that rpm???

I think your reading something wrong on there???? 
I think you were reading engine load when I had 0.66326 lbs of boost I was at 15.15469 AFR
I think ya thought my load number was my rpm or something

First of all, sorry, I am not a guru - no way, but I just happen to have some valuable info that might be of use.
Worst possible AFR to be under load is around stoich but it's OK so long as your just crossing over to the rich side and that's what is going on. For about 1.5 seconds however, right after applying throttle your going lean to like 17-1. It's not dangerous or anything but it can cause a misfire. If you richen it, just don't have it stay the 14's under load is all I'm saying.
I definately noticed with the stock turbo leaning the spool with the timing ramping downwards really helps it out. Just my perspective whether it has any relevance with your case

So your saying right after applying throttle when I'm about 17-1 it can cause a misfire OR...richening it to a lower AFR during that time would cause it to misfire???
also Soich= 14.7 right?
I appreciate ya'lls help

It would be better to log knock and timing as well, the map should get richer as the load goes up. Additionaly if you could get 2 byte load loged it would help as it's not to clear what load 18 psi on a GT35R relates to in load.
Aslo what fuel setup are you running

I can put my knock and timing on there also if that would help. it doesnt say knocksum though it says knock sensor voltage. is that the same thing??? my fuel setup is a double pumper with 2 walbros. one running all the time and the other one on a pressure switch that comes on at about 6-8 psi
