I've been thinking about picking up a Troyer tune just to see if there is a difference which it sounds like there isn't but Troyer just takes too damn long. I've been really happy with my VMP tunes.

 

I have VMP tunes and finally just recieved my Troyer tunes yesterday but haven't tried them yet, tomorrow I will install the Troyer tow tune before I leave with my trailer.

Having tried a Predator and an Edge on my 04 F150, these VMP tunes are WAY better, an actual noticeable power improvement and better shifting throughout compared to both canned tunes.

My 87 VMP performance tune was bang on, no issues and the shifting is much improved over stock. The VMP tow tune I am not so sure about yet, it pulls better than stock but I could here something at low rpm from the top end. Returned to stock and the noise went away...call it paranoia or whatever, but I haven't had a chance to really investigate.

I'll give an update on the Troyer tunes when I get a chance to use them.
