Currently my 318is has a cat-back exhaust system, a K&N air filter and a computer chip from a local BMW shop. I am thinking of getting my M42's intake cam re-dialled 5deg. advance next when I go in for a scheduled service.
What I'm unsure of is, will my car need a new chip or a re-tune to compensate for the changed cam specs? As far as I know, this chip only extends the rev-limiter 300rpm and slightly advances the ignition timing for better response.
Thanks in advance, Aaron
