GTM Supercharger Stage 1 w/ F.I. LTH

Sorry to be reviving this old thread but I came across is it and I think I am missing something here.

My dilemma is here is why Dreamer is making less power with LTH's. I understand boost = back pressure so freeing up the exhaust (CBE +LTH) will lower the back pressure (and therefore the boost) and make it more efficient, but shouldn't he be making more power @8psi rather than less?

Now it seems like this SC is capped @ 8 PSI. What that tells me is that no matter what you do to it, it cannot move enough volume to move more air than 8 PSI.
...

Now is it because the SC is capped @ 8psi that it can't achieve higher numbers or is it some VVEL thing holding it back?

Sorry, not trying to stir the pot just trying to wrap my head around this.

Thanks
