I loaded the Brenspeed 93 tune when I got my CAI and ran it for a few weeks - awesome! - and then thought I'd try the 87 tune. Ugh. Not as bad as stock, but it felt really sluggish. My wife even remarked that the car didn't seem to run as well. So I switched back to 93. Haven't tried the 91 tune. Wouldn't make any difference in my gas cost since we only have 87, 89, and 93 in this area, so I'd have to run the 91 tune with 93 gas.
