like the title says, does anyone know anything about the Venom vcn-500... i've been having issues with mine lately and not sure how to go about fixing it... ive been getting the error 2 code (o2 sensor) [just some back ground info... 2006 scion tc, headers and full 2.5 inch exhaust, due to the extra air flow i believe my o2 sensor is leaning out which is why the system wont load up... my question is what can i do to help remedy this, some ppl told me a wideband o2 sensor would help, some say no, some said re-flashing ecu or getting a piggy back fuel management would help, again others said no... you get the picture... please guys, i need help, thanks
