KR Gurus, need some info?
From a 70mph Roll It had .2dg of Knock.
Then I put in a yank and cashed in my JHcoatings refund and had my headers
re-coated. Now I have 0dg of knock off idle to 70mph and around 2dg from a 70mph roll. Somehow it flip-flopped. Does this sound right.
Everything was recorded using ATAP. I still have an exhaust leak post-header to work out yet.
