Custom Tuning | Karl Performance

Are you getting the most out of your vehicle?  Let our in house team at Karl Performance dial in your combination and get the most out of your investment! Dyno calibration is the best way to fine-tune a car for performance. Being able to run a vehicle on our chassis dyno, in a controlled environment, allows the calibrator to be able to see how the car/engine responds to various different situations your car will see on the road or the track and adjust for it.

Whether it’s carbureted or fuel injected we have the team and resources to get you dialed in. 


Carbureted: Cody Nadler

Fuel Injection: Robbie Massey


We currently offer EFI tuning for:

1997+ GM LSx, Gen V LTx Applications

Holley, FAST, etc. Standalone Controllers


Custom Tuning


Before scheduling your vehicle for a tune or any performance work, please look over our pre-tune checklist to make sure your car is ready for the tune process or performance upgrades. This will ensure that the time your car is here will be well spent, and will be leaving with a high quality tune:

-Vehicle has at least a 1/2 tank of fresh fuel that you plan to run

-Old/Dead gasoline must be removed from vehicle if it has been sitting for a long period of time

-Fuel filter is new or relatively new

-Cylinder leak down: you should not have cylinder leakage more than 7% on any cylinder. If you do then you will need to further test to see where the air is leaking from and to.

-Battery is fully charged (atleast 12.5v while running) and in working condition

-Belts are in good condition (supercharger belt is tight)

-MAF sensor has been properly cleaned and the o-ring is sealing properly in the MAF housing

-No vacuum or exhaust leaks

-Air filter is clean and in good condition

-Engine oil/supercharger oil is new or recently changed

-Tires are in good condition

-Spark Plugs are relatively new, in correct heat range, and gapped correctly

-Cooling system is in good working condition and topped off

-Vehicle is road-ready (no steering, brake, alignment issues, etc.)

-All sensors are in good working order and there are no “Check Engine” lights

-Check all fluid levels and also make sure there are no leaks. Leaks of any kind typically get worse once the engine and drivetrain is warmed up on the dyno


The additional stress/cylinder pressure realized after performance work or a custom tune will only exploit the existing problem causing further, and usually more severe engine failure. A good mechanical foundation is a must. No amount of time spent tuning will fix a bad platform. Following the above checklist will not only speed up the process but will result in a better ability for us to get your car the best tune possible.
