Go on 3gwrx.com search torqued performance, my name for my thread on TP, or his user name; eminehart.
I myself and running his stg 2 map. I and 1000+ customers have all proved Eric Minehart's maps are safe for dding. As long as you don't try to make tweaks on the accesstunerrace software it comes with. Leave that for a real tuner. It's been proven his maps pull harder and safer than cobb or perrins. Just read his threads and see for yourself.
Anytime you get new mods and you need a customized map, he'll gladly do it for you. He charges nothing for revised maps after you datalog and send them to him, but it's nice to tip a great tuner for his hard work.
Oh no, no. He's an individual tuner from Colorado that knows how to use accesstuner race software. The tuning software that comes with Cobb's AP if you purchase new or used. He also messes with Tactrix, romraider, etc. If you don't have an AP. If you go see him in person, he tunes your car via laptop and datalogging off AP or Tactrix/romraider/etc.
I believe the guy has around 1000-2500 customers worldwide.. iirc.
