Lars P Posted August 13, 2009 Share Posted August 13, 2009 I just spoke to a friend, he has a MC2Fore some reason we ended up talking about VTECOn my stock MB6 i have vtec at 6000rpmI just realised that everyone else has it somewhere around 4400-4800I went to the garage to see if it was a chipped P30 in my car but i just found the stock p9k, and it looks like it has been there since -97 Can it be the butterfly carp in my intake that changes the sound at 6000rpm?Can i chipp the p9k ecu ? i guess not//Sorry about my English Link to comment Share on other sites More sharing options...
civicturbo79 Posted August 14, 2009 Share Posted August 14, 2009 vtec on the mb6's is around 4500 rpm and it is thebutterfly in your intake that give you the 6000 sound change. Rich. Link to comment Share on other sites More sharing options...
