– OptiOne Engine Optimization
Custom-Tuned Engine Optimization
When you bring your vehicle to us, we always start by understanding your needs and expectations. Why are you looking to optimize your vehicle? Do you want better overtaking performance or lower fuel consumption? Maybe you tow trailers and need more power at low RPMs to stay in a higher gear even on inclines? Or do you just want to be the fastest off the traffic lights?
Whatever your goal, we fine-tune the optimization to match your needs. We call it custom engine optimization—something you simply won’t get with power boxes or generic, mass-produced tuning files.
Our Satisfaction Guarantee
If, for any reason, you’re not happy with the results, we’ll first fine-tune the parameters to achieve the performance you expected. If we still can’t meet your expectations, we’ll restore your vehicle to stock and give you a full refund. We always back up your engine control unit’s (ECU) original file, so you can revert to factory settings anytime.
Time will tell
Optimizing an engine involves adjusting hundreds of parameters in the ECU software. Your vehicle is full of control units, sensors, and processes that need time to adapt to the engine’s new characteristics. This means that performance will keep improving over the first few days. Let it settle in and drive for about 2-3 full tanks of fuel to allow everything to fully adjust.
