Are performance tunes legal in California?
Some are — we carry CARB-EO certified tuners that are explicitly legal in California. Diesel emissions tuners are not road-legal in CA, but emissions-compliant performance tunes are. Our shop at 9261 Bally Ct, Rancho Cucamonga is about 6 miles from Montclair — most customers are in and out the same day.
Will a tuner hurt my engine?
Quality tuners from reputable brands are designed to keep engines within safe limits. Stay away from extreme tunes for daily-driven trucks — the towing and performance tunes from major brands are reliable for long-term use.
Can I switch between tunes?
Yes — most modern programmers let you switch between tunes (e.g. economy, towing, performance) on the fly. We'll walk you through the options before you leave.
We serve these nearby locations for performance chips & programmers:
“Jake flashed an Edge Evolution on my Silverado and walked me through all three tune levels. The economy tune already improved my MPG on the commute and the tow tune is perfect for my boat. Exactly what I needed.”
“Got a DiabloSport inTune installed on my Coyote F-150. Ryan explained the difference between each tune and helped me pick the right one for daily use. Throttle response is much sharper and the speedo correction for my larger tires works perfectly.”
“Empire installed a Banks Power system on my diesel F-250. Floyd was very thorough about what's CARB-legal and what isn't for California. Ended up with a legitimate power increase and stayed compliant.”
