I bought the Turboxs HBOV as well. Also, put 4 washers in there. Only had one backfire under heavy acceleration. Mods are below...would the backfire most likely be from the new BOV? Or from the DP and MP? Or is it because of a combination of both? Not that the backfire scared me or anything...shocked my dad though! TEHEHEHEHE!
Oh yeah...Turboxs HBOV sounds amazing! For those that are considering
