can u de-restrict a 08 movano van?

I have an 04 plate2.5 dtci 115 bhp and have fitted a easy tune plug in box which I bought from DieselBob.co.uk, fitted myself in about 10 mins, just plugs into the end of the commonrail and gives 25% more bhp and really responsive no lag and no change to fuel consumption
