Who and What Our Company Does For You


Sound Performance is a tuning 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.

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.

New projects at Sound Performance now include supercharging and turbocharging of the new Nissan 350Z, Chevrolet Corvette, including the new 505hp 2006 Corvette Z06 and the exciting retro styled new mustang.The SP 350z currently has a ProCharger supercharger on it, and has since put down 400rwhp. We also have the first working AEM EMS in the 350z, which we've spent countless hours on creating the wiring harness, etc. Winter of 2006 we will be finishing our twin turbo setup for the 350z. Currently in the works are a C5 Corvette twin turbo kit, LS1 turbo kit, and a 4.6 Mustang turbo kit.

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.

Sound Performance is now going to make it easier to purchase our own custom fabricated products as well as 100's of other manufacturers products. We cater to both domestic and import markets. Our priority is customer service and complete satisfaction, as well as competitive pricing. If you have any questions please contact us.
