On a 99 GU 2.8 litres I have a MOTSON Chip which is similar to the UNICHIP.
The difference is enormous between 1300 and 1800 RPM. The torque nearly triple at 1300 rpm amd then ease out to only 20% more at 1800 rpm.
Remember this chip will cancel your Nissan warranty.
Email me privatly to know more about it.

Why, whats the secret

Guy replied:

The Motson chip has a big advantage on other "chips".
You can remove this Black box any time which means the Nissan warranty is still valid.
Actually this is not a chip but a printed circuit board encased in a black box.
It modifies / controls the EMC box externally. EMC is the box which control the Combustion, Emission and
Firing of the engine.
The total cost is $1400 all fitted with life warranty of the vehicle.
Probably 20% more expensive than others but it is fully installed, it works very well, the waranty of the car is preserve
and it has unlimited waranty.
