Sound Performance is a performance shop located in the western suburbs of Chicago, Illinois. Originally specialized in competition audio systems and custom installations, we began to branch out into turbocharged applications in 1990. Over the last 15 years, Sound Performance has gained the reputation as one of the finest tuning and fabrication facilities in the USA. From custom fabrication to top notch installations, we do it all.

Sound Performance has set numerous records for street legal, full weight cars. First 300ZX TT into the 10’s First MKIV supra to run 9.5 with stock Toyota Automatic transmission…. (A record still held today!!!), Fastest full weight supra in the world 8.45 1/4 mile, most powerful daily driven supra-1520 RWHP and now the fastest daily driven full weight Lexus SC300 in the country 9.59@143mph. Now we’ve done it again with the highest HP 6spd 350z 1248rwhp and Fastest 6spd 350z running a 9.35@158mph.
Not a day goes by in which the Sound Performance garage isn’t crammed with Surpas, Nissans, Corvettes, Mustangs, Vipers and other cars, along with engines being built, turbo kits being assembled, and electronics being installed and cars being dyno tuned.

Sound Performance’s facility now host a new 1750hp mustang Dyno. With wideband 02 sensors, pressure sensors, temperature sensors, and data logging capability, this Dyno along with SP’s trained technicians assure all customers of a properly tuned vehicle.
