I was browsing the HPTuners forums about my cavalier, and stumpled across a nice find. HPTuners now supports the 2012 LFX motors in the camaro, and should be supporting the 2013s. I emailed tech support to get the lastest beta.
If I can actually scan my 2013, and download the tune, I post up some screen shots.
Intrested to look at the trans tune. I do not plan on changing anything, but want to look at it and study it to see how different it is.
The only bad part is it is 4 credits, and most everything else is only 2 credits.
