Difference in 87 perf and 93 perf tune from 5 Star?

[pat'sRAPTOR]

I run my 89 performance tune all the time. I tried my 89 economy tune to see if my gas molar would go up and toy surprise it actually dropped .6 mpg in a week. So back to te 89 performance tune I went. Now when I go on runs I run my 93 performance tune and you can notice the difference plus I run Lucas oil fuel treatment in every tank so it keeps everything cleaned and lubed real nice!

Completely stock, can't tell any difference between 87-93.

Just loaded the 89 economy tune yesterday, since I was nearly empty and that's all we have available at the farm.

Too soon to tell on the mpg, but I can definitely tell on the performance side. Not nearly as aggressive on the acceleration profile as the 91 performance tune. My truck isn't stock either. I've got SW headers, lightning exhaust and a Volant CAI.
