I have a 2012 1500 with the 5.7, it has a 4inch lift and 35's with 3:55 gears and it definitely lost some of the pep that it had before the tires. Mainly highway driving and constantly having it shift is the issue. What would be a good option for tuners in this situation? I had a tuner on my 2008 Ford Expedition that almost ruined my transmission so I'm somewhat skeptical with tuners in general but if there's one out there that can help out with the trucks performance I would love to hear about what brand y'all went with and the outcome of it!
