“Hi Rev took that mess and turned it into a work of art. Theo was knowledgeable and great to work with.”

“He could tell by ear something was off — this thing runs like an F1 race car, no kidding. He dialed that truck in and I couldn’t be happier.”

“I’ve been chasing acceleration issues for 12 months… The lesson in all of this is go see Theo first.”

“Super happy with my tune on my ’79 C20 with the 5.3. Truck runs like a beast.”
