Re: "Wanting to kill the devil"
i have posted many times on the buick boards, that i tried a Alkycontrol , SMC and a DevilsOwn all on my car on the same day on the same dyno, and they all were within 5 HP of each other.. it manily comes down to price and preference, and customer service..
i was very happy with how easy it was to install and tune the DO kit..
