Looking For A Tune?

Intelligent Performance

ENGINE COMPUTER TUNING

New build not running right on the factory computer? Turbo not playing nice with those injectors you just put in? Tired of unneeded check engine lights and trying to bypass useless functions? We specialize in tuning / fixing all of these problems with HPtuners and many aftermarket ECU platforms from the likes of Holley, Haltech, Megasquirt, ECUmaster, and more.

2WD CHASSIS AND MOTORCYCLE DYNO

We have a 2WD low inertia eddy brake dyno in house for precise steady state tuning as well as max power runs. We can dyno any 2wd car and most motorcycles. Many AWD cars can also be put in 2WD temporarily just call us to confirm.

RACING PERFORMANCE

Don’t like slow cars? Neither do we. Whether its going around corners, winning cash in Mexico, or chasing that time slip at the drag strip, we have probably built a car for it or helped someone else building a car for it. We specialize in the tuning side of things but are no strangers to a wrench.

Intelligent Performance

Tuning in Sioux Falls

We are a tuning / performance shop located in Sioux Falls South Dakota specializing in GM, Ford, and Mopar pcm / engine computer reprogramming (formally performance chips / chipping) for anything from engine swaps to turbo builds.

Flex Fuel and E85

We have extensive experience modifying cars, computers, and fuel systems to run on midwest’s finest race fuel. E85! We even make sure your car will actually start in the cold unlike other tuners.

Other platforms

While we currently specialize in HPtuners and aftermarket ECU solutions such as Holley and Haltech systems. We also offer special rates for customers willing to let us create maps for other platforms.

Street Proven

Dyno Tunes are great but there is something to be said for actually driving your car and being able to tell your tuner exactly what you like and don’t like. We pride ourselves on our willingness to ride along with you and make things exactly how you want it. Some things like shift points are just better when you pick them out yourself.

Troubleshooting

When you build a racecar one of the unfortunate side effects is that stuff will break. Even worse is that most shops wont touch it anymore. We have seen just about everything and have gone so far as to hook an oscilloscope up to customer cars to troubleshoot oddball issues.
