What Tuner Actually Works?

So I already tried buying the Edge CTS2 Evolution and it wasn't programmed for 2014 5.7 so I sent it back. I badly need to get the speedo calibrated, I just looked at Hypertech and the site says it won't work on a '14 5.7 either. So what freaking tuner that calibrates actually works with a 2014 5.7 Express 4x4 with the 8-speed trans?

I'm starting to get frustrated since I wanted to buy the hypertech since it's cheap and would calibrate. I'm not wanting to spend a ton of money since I got the lift, tires, rims, flares, and truck in the past 2 months...I also have a buttload of "real life" expenses like the dreaded income and property tax to pay for in the next 4 weeks.

Diablo hands down. Hypertech sucks. Or if you didn't want a programmer for anything other than fixing your speedometer you could take it to a dealership and they can recalibrate it.

Download an app on your phone that'll tell you speed. They are pretty accurate because they go off of gps. That'll tell you how far off you are.

The dealership said they calibrated it already...definitely still off. When I'm going "35" in a 35 zone I'm passing people like crazy. I really only want the calibration and it appears the hypertech calibrated only will work. Since that's $200+ cheaper than a tuner...probably the route I'll go.

How did they calibrate it? Did they get the revolutions per mile for that specific tire? I emailed the tire company and got the numbers from them specifically for that tire.

No clue, I didn't ask. They just told me they had done it and that it should be close or dead on.
