Review on Enhanced Performance Tuner - Precision Parts Edge Products CTS3 Evolution 85400-300: Compatible with 2003-2012 Ram 5.9 & 6.7 Cummins Diesel by Chase Steele

Putting on my 2008 Cummins. My advice would be to save some money and buy Insight instead of Evolution and just use it as a monitor and buy good tunes. It freezes every now and then, which is a bit annoying but bearable. Nice big screen with lots of settings. And just FYI, these are not deleted ringtones. So don't be fooled.
