I have had a similar experience. I installed the Steeda CAI and Brents 93 race tune last May andran it for 11 months. About a month ago I loaded the 87 and I had the same result as you... It doeshave more torque down low though and I was at the dyno today and saw the actual results. I would characterize the87 as a torque tune whichpulls strong down low, up until say 3.5k-4k. The 93 that I ran pulled STRONG starting at 4k and right up to 6.25k. I believe that is the race tune. Maybe the91 is a performance tune but I can't speak to the specifics of it since I have not loaded it. That one will be next up for me.
