I put one on a truck when they where just starting to release it several months back. I had several issues with it and between the time getting edge to reflash it three time over the internet and actually installing it, it took almost 3 hours.:bang Now this could have been it was a new release and actually had to try different software versions till one actually worked.
On the other side once it was installed, it seemed like a decent tuner and gauges where ok. I wouldnt hesitate to sell one or put one on my truck but it wouldnt be my first choice but thats my personal opinion.
