Ok ive asked quite a few people and have gotten different answers. Im going big turbo in a few months and im looking for about 400whp. I know oem fuel is limited around 350whp, i do not have access to e85, and id rather not run meth as it will continue to be my daily driver. I have been looking into an aux fuel kit and im sure it can deliver enough fuel, but is it? Can i hit 400whp and not have knock with an aux kit on 93? Or do i also need meth due to octane. Thank you for any feedback!
