I have them working together. I wanted to see how the tune worked independently of the RB module, so i Zeroed out the RB map and then turned off the auto tuning. I was happy with the tune, but I was concerned my sprint carbon filter was leaning the A/F out some. since the RB is good with making real time adjustments, I turned back on just the autotuning to help out with air/temp changes, etc. and so far so good. RB really helps to smooth it out on the bottom end and virtually gets rid of all the bucking. Top end past 8k is ridiculous. Both seem to work well together after playing around with the settings.
