RB25 Stalls off Idle

[BoostedRBSX]

I just got my rb25 s13 tuned last week on Nistune, I was working on trying to get the speedometer on the cluster working(not sure if its related or not) and now I am having a major staling issue. When i put it in gear and try to go it just stalls. My wideband is showing it is loosing all fuel and going off the charts lean when I try to go. In nistune at idle the speedometer is showing i'm going 148 and when I rev the car that goes up, I cant remember if it did this before or not. Any input would be great because im stumped as it was running perfect since it got tuned and now i cant even move the car. Let me know if a video will help and ill take one.
