Why we love it:

Wow! This product may be one of the best investments I ever made!

You simply connect the box into the OBD2 connector of your car, and after a while of driving, the box takes information from your car's computer ECU and uses it to boost fuel economy or performance!

With the fuel saver box you can save up to 15% in fuel consumption which covers the cost of the box in no time and let's you start saving money!

For those who just want a high performing car and don't care about reducing your fuel costs, the performance booster box can boost power by 35% and give 25% more torque!

After trying these out, I was mad I had spent all these years driving without one!

The box alters the performance of your car (remapping) whilst remaining within the tolerance of your engine, so it causes no damage to the vehicle and doesn't exceed any manufacturer requirements. Plus, any changes are only in effect while the box is plugged in, so if you ever decide (for some reason) to return to your old engine performance, simply unplug the box and it's back to the way it was before!

It's really easy to install yourself, simply:

1. Remove the car key from the ignition

2. Find the OBD2 connector in your car and plug in the box

3. Put the key back in the ignition and turn it to the first stage (don't start the car yet)

4. Press the reset button (underneath the cover of the box through the hole in the top left) for about 5 seconds, then wait about a minute while it connects with your car's computer

5. Start the engine

6. After about 150 miles driving the box will be calibrated and start to fine tune your vehicle to either save fuel or boost performance, depending on which box you go for!

It really is that simple and works for any vehicle made later than 2001!

A complete must-have item which I can't believe everybody doesn't have already!
