Only problem I had was installing the file on my computer. After that it was a breeze and yes the support team was helpful and polite. You get what you pay for so for me the price is rite. The touch screen could be a bit more responsive other than that, GREAT!!! programmer. My 2010 regular cab TRX4 4x4 with the 4.7 blows my buddy's 2015 Hemi out of the water after dual exhaust,intake,performance plugs,throttle body spacer. thumbs up for Diablo.
