You press. It hesitates.
Engines leave the factory tuned on the safe side. You feel it as a little lag on the pedal — so you press harder, and keep pressing, just to hold your speed.

That gap is the lag you feel.

Same 65 mph. Less throttle.
With a sharper response you hold the same speed with less pedal and fewer revolutions. Fewer turns of the engine every minute means less fuel burned and less wear.

A loaded Mercedes-Benz Arocs heavy truck (2025/2026) ran the same route twice — once stock, once with the G44. Everything else stayed the same.

From Italy to the road
30 years of engine maps in one chip
The G44 was created by an Italian engineer who started in the workshops of northern Italy and spent more than 30 years calibrating engines and transmissions — cars, trucks, farm machinery and race vehicles — including projects with major automakers.
He built the G44 for drivers who want a better-running engine without touching the factory computer: you plug it in, and if you ever unplug it, your vehicle is exactly as it was.

Drivers who already feel it
★★★★★
“Unbelievable savings on my diesel S10. I also installed one on a VW truck: savings right away, and more power. I'm putting it in the whole company fleet — in just 3 months the savings pay for the chip.”
★★★★★
“A great device. I noticed about 10 to 12% lower consumption than I was used to, depending on the fuel I fill up with.”
★★★★★
“The engine got quieter, the delay when shifting disappeared, and it performs better without using more fuel — if anything, it's more economical.”
★★★★★
“I installed the chip and the result was great. More power, smoother shifts, more range and savings — and I'm driving with less than a quarter of the throttle.”
★★★★★
“I always felt a big delay pulling away from a stop. With the chip the car changed: it's quicker, and fuel economy improved on both ethanol and gasoline.”
★★★★★
“My car pulls better, I need less throttle and the fuel economy improved. It's even quieter. I'm really happy with how it drives now.”

Questions, answered
Do you ship to my state?
Right now we ship to Florida and Tennessee. More states are coming soon.
Will it work on my vehicle?
The G44 works on gas, diesel and hybrid engines, turbocharged or not, in vehicles that use CAN communication through the OBD-II port — in the U.S., that's 2008 and newer. It does not work on 100% electric vehicles. Some heavy trucks and farm equipment use a different 9-pin connector and need an inexpensive adapter.
Do I need an app or a mechanic?
No. There's no app, no Bluetooth and nothing to configure. You plug it into the port under the steering wheel in about a minute.
When will I notice it?
The G44 needs at least 8 starts and stops (key fully off) and around 60 miles — usually a couple of days — to learn how you drive. Many drivers notice a smoother, more responsive engine in the first 10 miles.
How much will I save?
It depends on your vehicle, its condition, the load and how you drive. In a documented controlled test, a loaded heavy truck used 11% less diesel on the same route. Drivers report anywhere from no measurable change in city driving to over 10% on the highway.
Can I move it to another vehicle?
Yes. It doesn't store anything and doesn't need reprogramming: unplug it from your car and plug it into your truck.
Will it turn on a warning light?
No. The G44 doesn't generate dashboard warning codes. If you ever unplug it, your vehicle works exactly as it did before.
What if it doesn't work for me?
Send it back and we refund your money. That's our money-back guarantee.
