Post both graphs, can help with figuring out whats going on?

Did you have to command more or less fuel at the same boost level as well?

^^x2.... did 4P CNC ur head? Or swap it with a core? Was it shaven at all? Like another person said above, a lot variables right now. I would also check cam timing as a "semi" quick troubleshooting procedure, since you swapped heads n stuff.
It could possibly be lazy as well cuz the port job likes or "shines" with another set of cams not exactly designed for NA.

I've attached the graphs, tune needs a clean up still. Been back to the dyno yesterday to check the difference without the intake spacer. Gained abit of torque but lost some Hp. Also ran out of injectors/fuel so we had to stop at 34psi. power is measured in Kilowatt and Newton Meters.

So U had to command more fuel. I'd be interested to see same setup with a quick downpipe swap to hood exit.
Did u gain SOME of your lost trq? Or u went on the + side from old stock setup? And now your HP is still chocked?
It's cool to look at these high output setups cause your max HP hits during the power band and not at end. So you have changed the dynamics of flow but not lift and duration and still trying to target that same power band for increases.
That second graph to the right is horrific! No pun intended. Hope u can figure this out.
Can't really tell which way the power band shifted on those graphs.

I’m just bumping this to see if you ever figured out what was going on. Was it the intake manifold? Or was it the head?
