Fun fact: According to the gentleman that sold me my bov (ecobash on instagram) he got it directly from Turbosmart as the prototype for him to test out and give feedback on. Everything checked out as it should have and they let him keep it. He favored the sound of the 50/50 one so he only had it on his car to test it for them and than took it off and put the 50% one back on. He put it up for sale online and i saw he lived 15 minutes away and now ive had it on for roughly 10k miles. Fun little mod.
