I am more than convinced on the Hfs-3 just because Miguel, Jerry, and Orlando swear by it. And they all have fast cars lol. I am new to meth injection, and I know you get what you pay for, which is why I wont waste my money on a cheap kit with no fail safe. I guess, for all the positives about it, and more power I can make with pump....its well worth the money. And Z, what daily..the vw you bought a while back? and I'm getting your wheels from Justyns house today.
