I thought it felt abit spritely

Dieselderv , a lot of these boxes simply fool the ECU & come MOT time the new regs will probably lead to a fail . If you are not sure , ask your local test station to do an emissions check .

It could save you heartache later

As an MOT tester , I "find " these in place & have to issue fails due to smoke in excess of manufacturers plate limits ( square box found on VIN plate or a square sticker with numbers printed on it .

A real improvement is a rolling road remap that is specific to your engine

If plug in boxes were so easy , everyone would do it rather than spend fortunes on equipment & rolling roads

Hi do you know if this box just puts more fuel in or if it increases the turbo boost as well, as if I does that will limit smoke,
what model/ name is the box, Thanks Dave

My mot guy is a nice chap if something simple hell do it there and then ..if he can't carry out the full test hell ring me to let me know and not charge,and give me a chance to repair before charging me. If he spots it and it not allowed he will remove it then carry on the test..il have a look again later but I'm pretty sure it just said pbox tuning box on it
