Is it? If you can't trust them to build a motor properly, then why should anybody trust them with a tune especially since they just started created tunes for this platform. I know I wouldn't and a lot of people don't as well.That's far different than a tune. I've had nothing, but fun come from their tunes. I've been running their Trueflex Stage 2 on e85 and my car is going healthy and and much faster.
