GIAC Chip problems
 

I sent my ecu to awe early this week and received it back a couple of days later. I took it for a ride and noticed it would like skip at some points alot when I get up to high boost like 15 pounds, but it just got worse now my car like sputters and does this little back fire thing when I reach 7 pounds of boost also my check engine light has come on. I was wonder if anybody has had this problem or might know whats wrong it kinda feels like its not getting enough fuel?

Did you re-gap your plugs? Or better yet, gap down a new set and install them? Stock gap I believe is .032" but under a chip, you should gap down to .028" to fire through the extra cylinder pressure.
