I considered the other tune options with Unleashed being the biggest consideration, but ended up going with 5Star.
A few years ago I built a E350 and needed only the transmission tuned, no motor tuning and 5Star did a great job. Since I had a positive experience before, I returned.
I'll keep an update going about the tune. Just got the truck last week so the only mods done so far is the cat back exhaust, leveling kit and blow off valve (for noise only).
