I had a consultation with him regarding my car build and was extremely impressed. He’s very informative, incredibly knowledgeable, and—most importantly—everything he recommends is backed up by real-world experience and actual track data. He doesn’t just repeat internet theories; he explains why things work and supports it with numbers and results. If you’re serious about building a car the right way, this is the kind of expertise you want guiding you.

Justin tuned my 15 silverado and it drives like a completely different vehicle, feels like how I thought it should feel. He did an amazing job with the transmission, it shifts gears so great now. His attention to detail is amazing. I am very satisfied, well worth the money.

Justin is excellent. I have no experience tuning or even with computers for that matter. He's Confidence inspiring and very calming. Without His reassurances , I would never attempt this.
Outstanding.
