Having just found out that my car cannot be mapped (a person may have figured out how to), I have become despondent!
My car is currently running a 2.25" exhaust complete with Lexmaul 4-1 200 cell sports manicat. Is there any point in doing anything else? Can't see cams being any good now as they can't be mapped in. Really wanted 190-200 bhp out of my Vectra C. Love the car and will not sell it, just want more power!
Can anyone give me some advice on which steps to take next? Need some gurus who fully understand these engines lol.
