Hmmm bugger! Mine is 52 reg so a very early Vec C. I'm sure some Vec B's were registered on 52 plates also as this was the cross over year (2002). The early preface Vectras were half canbus. (From 2002 to 2005), after that they were full canbus models.
Another question then.......Is there much point modifying the engine I.e. Inlet, cams etc if I can't tie everything together with a map. Will it run poorly as the mods will not complement each other?
Or....
Do I just fit a 50-75 bhp nitrous kit and enjoy it?!
