I had my motor perfectly tuned at 15 pounds of boost with a stock turbo with no knock at all. But after I installed my new ta49 I am starting to get some knock. Its set up to about 14 pounds of boost. I have everything set up the same. Do I need to bump up the fuel or something? Its running about 810 on the o2s at wide open throttle.
