GFB Mach2 T9111 with Pierburg. I only used them both for a couple weeks. There is nothing wrong with either of them and both work the way they are supposed to. I simply decided to stay with the oem setup. I will sell them for $125 shipped. New price was $210 GFB/Pierburg. I have all the original packaging for both.
