Default Dynoed setup power seems low/Update tune posted

Engine Is 6.0 flat top pistons L92 heads with light clean up and milled 25 thousandths with stock ls3 head gaskets ,Ls3 intake ,long tubes and GM hot cam.And before we start bashing the hot cam I did my research and I know there are a lot of other cams but the hot cam fits my needs.

Should this combo be making more or does the power look good

The graph is wavy which tells me there is an issue.Could be electrical or tune. The curve looks low like the cold air might be restrictive at a stand still dyno.

Yes, the hot cam does suck bad in a LS3 but should still make 400rwhp.

That's basically what a bolt on 364 should make. You have better heads/intake a bigger cam, so there's no reason why you shouldn't make more power.

I would also question the intake tube and filter, as unless there is a mechanical problem with the engine that seems to be the only sub-par part.

What sort of MAP and IATs are you seeing on the dyno?

Default set-up

Iat's were show between 70-80 and the map readings showed that there is no restriction in airway.The engine has 611 miles it is completely fresh.Trying to get the tuner to send me the tune so I can post to see if people see any issues because this set up make almost the same power as my 6.0 with ported heads intake and full exhaust

The inlet is a problem.Bends ect hurt airflow. Step it up to a 4" pipe.
