Scheid Diesel didn't test the Blue Chip against the TST PM3, I did, on my truck. But the whole thing was instigated by Rob Swartz at Blue Chip, and Dan Scheid stepped in to make everything possible. 4 dyno runs was all I wanted to do that day. Once I get a few other things on the truck ironed out, I'll be calling Edge Products to try their box against what I have now, on the dyno. I didn't give them a chance at Scheid's and regret it. But knowing the high caliber of their products first hand, I'm sure it 'll kick butt into the next county.
