While we can't comment on other people's tunes, we break the mold on these trucks as we have our own proprietary hardware and software for tuning them.
Throughout the years as we've continued to offer more unique products, like our stroker engine, camshafts, ported heads, etc. We saw that we have outgrown the capability of commercially available software. We found there were just too many errors, omissions, and often complete lack of support. Due to this we were locked in a holding pattern on pushing the envelope any further on several platforms we support. This is when we made the move to our own offerings. By doing so it allowed us to gain exceptional understanding into the vehicle's logic used for calibration.
This is why so many companies throw in the towel on tuning these trucks, and ship them off to us to complete, or buy our tuner with our remote tunes.
Just a little insight into why we blazed a new path in a completely different direction from the rest of the crowd.
