I second that^^^! Chris has a wealth of knowledge as far as diesels and performance and his wife probably knows more about the duramax than you do! Lol Good service, knowledge, and quick turn around on repairs/upgrades! Hell he built my tranny and tuned my truck in 1 1/2 days and no problems or complaints. Needless to say I'm very impressed and would highly recommend them! Plus, when I was running 285's there wasn't any duramax's that could touch mine that I ran across with just a tune or programmer.Really the only shop I'm aware of in the area is Relentless Diesel Performance in Willis, TX. That's who did my tuning. It's about an hour drive from College Station.
