Yes, I can't say enough about Chris. His tune is spot on and you cannot ask for a nicer guy. He built the motor for me too. And this thing is a monster. There is still a lot left in this truck but I wanted it to be street able as well. With a 727 a bigger stall and a trans brake I could gain a few more tenths. And I can guarantee that's in my future. But I'm just enjoying it for now.
