Yea that's about the skinny of it, for those that have access to the metal member section it's all detailed in this thread. Don't trust your engine with dramatune, Facebook gives him way to much of a following.Tldr he has no idea what he is doing
Short history
blew up about half of the motors he was tuning in a span of six months
Tuned a full bolt on upgraded turbo car that put down less than a freektune ko4 and told the owner it was fine
Was caught copying tunes from other tuners tweaking a few parameters and calling it good
Cant successfuly get a MAF calibration correct
That's just what I remember off the top of my head and I don't have Facebook so i missed most of the drama
