I was driving tonight and had the ultimate set on T1-16. I got on it pretty hard going on to the freeway and it knocked like never before. The led was flashing so fast it was solid. It has never knock so bad before to were I could hear it. The truck is driving fine other than when I get on it. So what I need is to use someones datamaster and check out what my truck is doing. The plugs, wires, cap and rotor have less than 2k on them. Thanks
