What we do

1) Custom steady state dyno tuned ECU’s by professional certified dyno tuners. Certified by EFI University, with the latest software and technologies available.

2) Sales of pre-tuned engine packages. Many people want a product that they know will work. If you buy a cam or cam/head package you want to be able to bolt the parts up, plug in the ECU and go. Lethal Injection LLC will only sell prooven combinations that meet our quality/repeatability standards.

3) Product development for engine builders. This would include setting up cam/head or complete engine combinations for mass production. Contact us for more information on procedure and pricing.

4) Mail order tuning. Many times customers want simple upgrades (More horsepower, fan on temp, thermostat, spedometer recalibration). A mail order tune is a simple and effective solution. 

How can a mail order tune help my custom build? Here we can get you up and running. Though not perfect, a quality mail order tune will get your car close enough to run and collect the data needed for refinement. Customers will be sent calibrations via e-mail, or uploaded on site depending on the customers personal software/ hardware capability. See our list of supported ECU's

How we do it

We are taking a more scientific approach than our competitors. Most of the tunes out there are a hodgepodge of band aids and guesses. Our goal is to produce a quality calibration, and be able to explain how we got there. We are methodical, and not vehicle biased. Steady state tuning is how we stay ahead of the competition. By holding the car in its various load cells we can determine the fuel requirements, as well as the timing requirements for the best possible torque application.
