Box in my car I seen a company that does them racechip.co.uk has anyone
Heard of them or used any of there chips any information would be helpful

Chips or rather resistors fool the ecu either at the fuel rail pressure or fuel temperature sensor to dump more unaccounted fuel in .

Hense you always see a false mpg gain .

From racechip or know of a good one that they have installed
