Hows 93 compared to 87? What exactly is different the shift pattern or is there truly a difference in power?

Hows 93 compared to 87? What exactly is different the shift pattern or is there truly a difference in power?
The 93 is dialed in for maximum performance using the higher octane. Same Street shifting in all my 5* tunes since it is so perfect for daily driving. Night and day difference between 93 and 87. Acceleration is much quicker, pulls out from start much quicker and smoother and requires much less pedal to pull out from stop, make a pass or accelerate uphill. Very little pedal required to run 45-50 mph. The 87 however is a noticeable difference over running stock tune!
I like my 91 tune better than the 93 tune.Seems like the truck run better and shift smoother with the 91. 93 tune shifts all over the place and the power isn't there.
I've been running Daily Street 93 for 2 weeks now and I like it, only thing that annoys me is when Im on the highway @ 120 km/h every 30 sec the truck would twitch a little like its a sudden downshift or a throttle release if you know what I mean, nothing big just a small twitch for a second then back to normal.
Maybe its lacking fuel? spark thing? or because my tunes were set with the roush CAI in calibration and Im currently running stock intake? although Mike from 5* told me the stock intake will work with my tune without the need of revision.. I know this is caused by the tune because when I returned the truck back to stock it went away.
