Most likely definitely the case considering it was my first attempt at tuning. The complexity of the aem software is pretty intimidating for noobs, but that's also what makes it so useful in the right hands.

 

Hmm... So far on KPro I'm seeing around 24 mpg. I need to track a few more tanks, but it's not quite as high as I thought it would be. One of the challenges I'm having is my idle AFR is all over the place. Sometimes it's perfect, sometimes very rich, and sometimes very lean. Since it only seems to affect super small pulse widths (and not normal driving), I'm think it's probably an injector characterization problem.
