I finally got to test drive my truck today. Let me start by saying it's SMOOTH! No more rattle under acceleration, low end improved somewhat. Still not EXACTLY what I thought it would be, but definitely better. I do have a check engine light on, DTC says "U12A4 communication with ammonia sensor". I got with Ray, he's going to make some minor adjustments. We work these few bugs out, and I'm sure this warp tuning will be awesome. Thanks again, Brian
