Vauxhall Astra Diesel Superchip .

Plug and Play Superchip for Deisel Astras only!!! Overrides ECU and does not affect warranty. Simply plug it in and expect gains of up to 40BHP... as Simple as that! Very easy to install, only takes about 2 minutes. For example... if you have an astra diesel giving out 120bhp, plug this in and then your horsepower will be boosted to more than 150bhp. If you plug it in on an astra producing 150bhp, then this would boost it up to almost 200bhp!!! Simple but very effective peice of equipment :)
