A lot of people said there was no need to replace the ported TB and to just run the stock one, that since I am on a blow thru setup (Centri for a Procharger D1SC) I wouldnt see any gains at all. The engineering side of my brain struggles with that mindset as even the shop that did the initial install of the D1SC said there are no gains for TB or intake manifolds on Centri cars. I decided to test the theory.
I purchased a brand new ported TB from Soler Performance, got it installed and relearned. Then I proceeded to start pulling some data logs. Those logs confirmed my hunch.
While yes the system is a push thru blower and not a pull thru blower the car still saw an increase in airflow versus what the previous ported TB saw for the same temps and conditions.
Now to get the car on the dyno once some cooler weather comes around and I get the A/F cleaned up and see what kind of power it is putting down. Hoping at that point to hit the track as well for some better times as well versus the last time I was out there and running on a dying LPFP.

What was the Baro readings before and after?
Air density have a huge effect on Total Air flow through the engine.
