I've been running a 93 PRX tune from MPT for almost 2 years. The tune isn't magical, but will say it offers a significant change in performance on the top end of my v8 5.0. With the added throttle response change, the truck definitely gets up quicker. The best part of the tune and sport mode, at 80mph I can jump to 115mph in no time at all. 0-60 seems slower than what I initially expected, but overall quicker than stock.
93 has become increasingly expensive. I've done some research on the ethanol side. I like the idea of e85 but don't want the massive drop in fuel economy. Was curious if anyone as some insight or has ran some tests on e85 blended with 93 or close to it.
