Didn't get a chance to try the Diablo tune since it wasn't playing nice with my work laptop, but once I got home on a different computer it updated just fine. Below are the results from yesterday:
386whp/406wtq
WHP is just a touch lower than I was expecting, but WTQ is about what I figured. For comparison, stock C7's are putting down 410-420whp on Dynojets.
