Throwing code 2290
 

was on my way home today and went to pass a car,got on it pretty good and check engine light came on..got home checked the code with my sct programmer and says 2290 low pressure.. cleared code,restarted didnt come back yet..mods:4 inch turbo back,air raid intake,sct programmer,and EGR delete 1 week ago..any ideas?

I think that may be a quirk of tuners. My Excursion does this as well but only when I have my evolution on it. Put it back to stock and try it again....
