Nitro OBD2 Performance Tuning

Plugged this into my Jeep Grand Cherokee 4x4 4.0L straight six petrol automatic, as you can guess I'm trying to improve fuel economy.

Before using it I had been getting 17.9 - 18.3 mpg

After using it for the last month I can now say i'm getting between 19.7 - 20.4 mpg

It doesn't look much but it is at least 10%, if I was driving a car doing 35 mpg it would in theory bring it near to 40mpg.

Best £20 I've spent on the old girl yet!

Improved performance for tiny cost

Not earth shattering but a noticable difference with improved pickup and smoothness so well worth the money. Only downside the whole unit glows and it stays lit all the time even with engine off and doors locked.Read full review

good luck

Bought this product installed it after driving 200 m the transmission got confused which gear should it be in
maybe the ECU got REMAPED and it was all on took it the mechanic had to clear all codes
decided to install it again the car is running fine at the moment not sure of the extra power but just an extra yellow light near the foot
so cant really write a review on it i guess its just a cheap thrill (i think)

improvement

Simple plug and play ,I have always watched my MPG and was an average of 36 I've used this for around 400 miles and currently getting 43.
the best result was a 100 mile motorway journey getting 47 MPG.

my car (a 15 yr old Picasso, 1.6 petrol) even does feel nippier on the acceleration and even has more oomph for the long winding hills.
