Welcome to MAC Autosport, Colorado’s Premier Dyno Tuning and Full Service Speed Shop.  Thank you for visiting our revised website.  MAC specializes in dyno tuning most makes, and offers specific support for Mitsubishi EVOs, Subarus, Nissans, and Infinitis.

Our All-Wheel Drive Dynojet is the busiest in the region, and our shop sells and installls  performance modifications for engines, turbo systems, supercharger systems, suspension upgrades, driveline upgrades, and brake upgrades.  Check out this site to find out what we’ve acomplished, and what we do best.  We always strive to provide the best merchandise available, and  installations performed to the highest possible standards.  Our goal is to maximize our customer’s driving pleasure.

While we will dyno and tune any and all vehicles, MAC does have some specialty areas of expertise.
Our specialty vehicle makes are outlined below.

MAC always has NISSANs in the shop, either for performance upgrades, JDM engine swaps, or for tuning.  We are acknowledged as the destination shop for 240SX swaps in the the Rocky Mountain region. Our SR20DET engined cars are not just daily drivers (although quite a few are), but also compete in autocross events, drift competitions, track days, drag racing, and road race competitions.  MAC is drift HQ for the region, and our drift car, driven by Adam McMahan, competes all over the west.

MAC sells, installs, and dyno-tunes turbocharged or supercharged modifications for G35/350Z models.  MAC is the authorized dealer for Stillen in Colorado, and fully supports the G35/350Z.  We have just begun tuning with TurboXS UTEC for the G35/350Z, with very impressive results.

Don't limp around with a bad swap - rely on MAC to build you a car that adds up to FUN!

MAC dynos and modifies more Subarus than any other car make.  We have had more than 300 different Subarus in our facility, for tuning, power upgrades, suspension upgrades, drivetrain upgrades, and brake upgrades.  MAC stocks and installs UTEC from TurboXS for tuning Subarus, and also sells, installs and tunes Cobb AP, Hydra, and Autronic for these cars.  We are Master Stocking Dealers for Perrin/Alta.  Whether your objective is a modest power increase, better handling or stopping power, or if you want monster horsepower, MAC has the practical solutions for your Subaru.

Mitsubishi EVO 8/9

As of mid-year 2006, MAC has had more than 95 different EVOs in the shop for Dyno-tuning, or for installations.  Our projects have included numerous HKS cam installs, full engine builds, stroker engine builds, suspension upgrades, brake upgrades, clutch upgrades, and turbo upgrades.  We have seen any and all combinations of modifications on these cars, and we know what works, and what doesn't work.

MAC proudly carries the performance upgrades that have passed the test on our Dynojet, from HKS, RPS, AMS (Automotosports), ATP Turbo, MAP-ECU, RC Engineering, Hawk Brake, and more.  Don't make a costly mistake on Your EVO, stop by MAC and we can discuss your power, handling, and stopping goals.
