Level Two Towing, no power gain

[fordkindaguy]

Ok so i took the truck out and ran the canned level 3 tunes just for a couple minutes to see if i could feel any difference... i ran a 0-60 and it dropped me down about half a second. 7.66s I didnt really feel the difference off the line though =( i know it could be the cai problem but i figured i would have felt something on the lower end. I was curious when i get the 93perf custom tune will i really feel it? Through the whole power band? thanks for all the answers so far and if anyone has an opinion on this let me know!
