Hi,
I have something similar...its more of a tuning box- i bought it of ebay a few months back for my vw transporter van......it boots ur bhp and torque and the results are amazing, the turbo boost i get sometimes hurts my neck when the turbo kicks in.... it kills ur fuel consumtion though....but worth it when your at a set of lights and you know youve got that extra power if needed
