I have a 98 a4 1.8t Q. I want a chip but am unsure of which one to get. I was told that apr chips are good, however after 5,500 they cut out. They pull real hard from 1st to third, but once in 4gear you can bearly feel the difference, is this true? I was debating on this or a GIAC, i want the most bang for my buck, and the most reliable, any help would be greatly appreciated
