Limp mode 1 week after install of JB+!?

On the way home from work yesterday I got the dreaded "Engine Malfunction: Reduced Power" message. Has anyone else gotten this with their only mod being JB+, not altered from the factory middle setting?

Is it almost certain that since it induced this limp mode I have a code thrown?

The circumstances: It was very hot and humid here when I was driving home, I had the A/C on "Max" for parts of my drive (only about a 20 min drive) and the engine malfunction message appeared in the last 5 minutes or so, after some WOT driving and possibly not fully warmed up yet. I got the message while I was about to pull off the highway and honestly, the "Reduced Poer" didnt feel nearly as reduced as I would have expected. When I got off at my exit and there was a red light I turned the car off and on again. No long cranks although the idle seemed/seems a little rough (then again this seems to be true of bone stock n54s).

Any thoughts? My main concern is that I threw a code.
