X4 Programmer
Had to download their update drivers, that was a big hassle. Then had to install updates to programmer. (8hrs later) After all, that updates failed. It's been 2 weeks and still not installed on my truck. Tried SCT Performance emergency weekend tech. support, no answer. Sent e-mail to SCT, no reply.

Vehicle Won't Start
I installed this on my 2011 Toyota Tacoma and it was working for a bit until all the sudden mid drive my truck completely shut off, still haven't been able to start it.

Even Better Than I Expected
It changed almost everything about running my Ram. The tuner made it perform more like a sports car. No way I'll go back to the factory tune. Best aftermarket accessory I've even tried.

Does Its Job
Quality products but could be more user-friendly. The menu of the tuner is a little confusing and you need quite a long time to figure out how it works. However, I really like the performance tune and think all the pre-loaded tunes are very good. Hope SCT will do some improvements.

Decent) But no Wow Factor
Although this product is not bad, I expected a bit more. First of all, I want it to be more user-friendly. I had spent quite a lot of time to figure out how to use it. Has lots of options to control almost every aspect of my car. With this programmer, it does feel sportier. But to tell you the truth, I thought the performance gains would be better. I noticed an increase in throttle response and acceleration, but I was a bit disappointed with the HP increase. Not fully satisfied!

SCT Livewire TS
It is very easy to hook up and tune your vehicle as long as you actually follow the instructions. Only down side for me is I cannot not correct my speedometer because my tires are 46s and according to a guy I spoke with from SCT the computer only allows you to tune to 34.5 inch tire. I tuned it for 87 and my mpg seems to be a bit better and you can definitely feel the extra power in the truck as well.
