Alright this winter my ex with sohc is going under the wrench, with boost, and my buddys says his car wilol still be fast because my o2 sensor will only take up to 1psi, w/e im going with wideband O2 anyway doing my **** right! but i was wondering if there was any truth to that or if he is pissy cause me ex with basic bolt ons is beating up his mostly stock Si. thanks

 

WB02....1PSI......read up buddy if you want to beat him
