As I'm nearing 60K miles and will be out of the Ford warranty, went a head and got the RTD device and custom tunes from MPT. I went with the PRX 91 and daily tow 91, both tunes smoothed out my shifting and no more skipping gears as it now goes though 1 - 10. I love it. Their customer service was also great, email or calls. The 91 PRX makes my truck feel so much quicker and lighter. I think I prefer the 91 tow tune for daily driving as it's a little more tame on the shifts. We don't get anything higher than 91 octane here but I bet the 93 tunes would be even more potent. Very satisfied with MPT.
