bought myself a 2004 2.0dti vectra C, as soon as i bought it i took her straight over to get remapped.
to my absolute horror i was told it cant be remapped!!!
so i ave heard bits and pieces about a tuning box for them but dont know anyone who has one on there veccy C 2.0dti.
Are they really easy to fit as i heard they have to be wired into the loom and not a simple plug fit.is there much of a difference in power and torque?what is the most power i could expect out of a tuning box?? is it worth while getting one???????????
