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 13 miles from Riverside — 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:
“Had an Edge tuner installed on my diesel. Empire walked me through the tune options and helped me pick the right one for daily driving and towing. The truck pulls way better now.”
“DiabloSport tuner on my Hemi Ram. Empire flashed it and made sure no codes popped. The throttle is sharper and the transmission shifts better. Solid work.”
“Got a Banks Power tuner installed. The tune options for towing vs daily are great. Empire took the time to explain everything before I left.”
