From stock cars to 1100+ whp daily driver cars, We've done it all. When it comes to late model Mopar ECUs, nobody has more experience than us. We were the first to custom tune late model Hemi motors, and continue to set the standard of best in the business. We have made more horsepower and tuned more Hemis than any other late model Hemi tuners, while maintaining superior driveability, period.

What is a Custom Tune and why do I want it?
The late model Hemi ECU is a complex piece of equipment. While it is very good at "learning" a new environment, this "learning" does not happen at high load situations. So while your car may start, run, and drive like normal, it doesn't necessarily mean it is operating properly. A smooth running car may be running more dangerous than you think. The Hemi ECU uses a Volumetric Efficiency based fueling calculation system, which while very accurate, does not adapt well to changes. The nature of this system relies on a pre-defined efficiency map that fueling is calculated off of. When you change your intake, exhaust, or anything that alters airflow through the system, you are altering your volumetric efficiency, therefore producing an innacuracy in the fueling of your motor, that your ECU is un-aware of. This can lead to less than ideal lean conditions that can lead to not only large ammounts of knock retard, slowing down your car, but power loss in general due to incorrect fuel ratio, and dangerous lean conditions that could possibly cause premature motor failure. Heads and cam cars require even more radical changes and often will not even properly run without a custom tune. Custom tuning typically will yield 15 to 50+ horsepower gain at the wheels depending on the vehicle's setup.
