id like to bring some attention to this. do cams advance timing once installed? jw. are they required to be tuned? i had them installed and car runs smooth along the rpms. not sure if it improved performance feels really fast up top. dnno, just like some info, because they caused some wicky things to happen to my nitrous. do i need a tune or tne them?

 

no... your cam timing settings are still the same as the stock... it will not change until you tune that with an aftermarket ECU...like MoTeC or a custom ECU cam timing table reflash...

cheers,
