Modifying Tune. Lean/Rich

[SeaRay45db]

I have Yukon Denali with a 6.0 L. After I put a CAI on I started throwing P 0171 and P 0174 codes. I know I don't have a leak, because I have to change brands because of other issues. When I put a time only, still get them. Taking with others, they have said just change the mix.

Now this sounds silly, but just to confirm, when I want to burn richer, or add more fuel, I would add 5%? Reason I ask, is I thought someone told me is that on the I2 you actually move the needle towards leaner if you are burning leaner to get the mix right.

Thanks!

you should use the injector slope adjust to dial it in, see the sticky thread in the predator section for how to use the tool to log and adjust.

Thanks
