Lund says logs look perfect. The manifold is a brand new 20' take off. No cracks. My only thought is that i have lower boost and power due to maybe not revving it as high plus the boost loss due to the manifold being less restrictive. Car drives good.

Shouldn't you be revving it higher with the 2018+ manifold?

You can,yes. This was a data log revision lund wanted 2500-7200 wot

Bringing this back up but did you find the issue? i Installed mine and well i lost to the same car that i went neck and neck VS prior and i also got a CEL P0300 and it went away after 10 seconds from the pull.. felt like it just stopped pulling midway

P0300 is random misfires so that would explain that, you were losing time due to pulling time ...

yeah which is weird, i changed plugs which were causing issues previously.. but i did the manifolds swap, i hear that the intake runners can breakand cause that code but mine are locked out well with zip ties.. i did the install, and its straight forward unless i messed up somethinf

I believe it your tune. I also got the PO300 code when trying to tune for CMCV delete.

The only way I can do it successfully is to license a Roush tune. And the things they change to make it work are not visible to me

Well share some information

The changes are not visible. This might be the reason for the added cost for a manifold change tune. They are buying a Roush tune.

I could be wrong and people are living with some minor drivability issues below 2000 RPM
