Friend put a cam in his 6.0 truck from texas speed 220r small cam didn't want nothing big just wanted a good idle. He had them tune it after and it never idled right and had a dead spot around 4500rpm. scanned it and seen it was seeing a lot of KR. so I uploaded a stock spark table in it and bumped it up 2*. and don't see any KR anymore but has a bog off idle wont just get up and go. Just wondering if someone can look at this tune and see what else I could do to help him out. Novice tuner still new but learning quick.
