Hi guys, after always having performance cars i took a huge step and swapped my Evo 8 for a RR l322 3.0 Diesel. Obviously its a totally different beast but upto now im enjoying the drive. I do have a couple of questions to ask.....How do i zero the trip computer? ( the display that shows average speed and milage ) and also the guy i got the RR off also gave me a thingy ma jig that he said would increace power when fitted. Its boxed and has never been used....its called a "tunit V-CR" for BMW and Range Rover. Has any one heard of or used this product? Also why do some Range Rovers have Two vent Fins and Some Have Three? Oh and wheres the cheapest place to buy Chrome type bling? Second Hand 22s ect....Thanks guys in advance. Hunter
