Fuel Savings
Use the New Potential
No optimization will reduce fuel consumption automatically. However, what you’ve now gained is the opportunity to save fuel—if you adjust your driving style to match your engine’s new capabilities.
How Much Can You Save?
Most drivers can save between 10–20%, and in some cases even more.
The amount of fuel you save depends entirely on how you choose to drive after the optimization—and how well you take advantage of your engine’s new performance curve.
Results also vary by engine type.
Turbocharged or supercharged engines typically offer the highest savings potential.
Naturally aspirated engines (without forced induction) generally see smaller gains in torque and horsepower, and therefore, more modest fuel savings.

Watch Your Right Foot
It’s easy to get excited by your engine’s increased power—and if you consistently push it hard, your fuel consumption may actually increase.
But if you adjust your driving habits to take advantage of the improved torque curve, you have a very good chance of lowering fuel consumption without sacrificing performance.
Drive at Lower RPMs
In most cases—especially with turbocharged engines—we can significantly broaden and shift the torque curve.
This means more power at lower RPMs and sustained torque over a wider range.
As a result, you can:
Shift up earlier
Downshift later
Drive in higher gears with taller ratios
All of which reduce fuel usage and mechanical stress.
Stay in Higher Gears
Hold off on downshifting. For example, instead of dropping to 2nd gear when exiting a small roundabout, you can now stay in 3rd and still maintain the same power output.
The same principle applies to overtaking: Instead of dropping one or two gears, you can often remain in a higher gear and still accelerate faster thanks to increased low-end torque and longer gearing.
Driving an Automatic?
If your car has an automatic transmission, it will gradually “learn” that there’s more torque available and won’t need to downshift as often—especially during overtaking or when accelerating out of corners or roundabouts.
⚠️ Avoid kick-down.
Flooring the throttle will force a downshift to tap into high-RPM power.
After optimization, you often get better results (depending on speed and vehicle type) by pressing the pedal about three-quarters down, instead of 100%.
With some practice, you’ll learn exactly when your gearbox wants to downshift—and you can apply just enough throttle to avoid it, leading to:
Quicker, more efficient overtaking
Less engine and transmission wear
Lower fuel consumption
Real-World Examples
Boats:
More low-end torque means your boat planes faster—a normally fuel-intensive task. Once up on plane, less throttle is needed to maintain cruising speed, resulting in lower fuel use and less wear.
Some customers have even upgraded to a higher-pitch propeller, enabling lower RPMs while maintaining the same speed.
Motorhomes:
Optimizing motorhomes often makes a huge difference. Where it was previously difficult to maintain speed uphill in higher gears, the increased torque now lets you stay in gear without losing momentum.
That improves comfort and reduces both fuel consumption and wear.
