Looking for Input: 370 Motorsport Data Logger

Oh crap, I almost forgot. Logging EMAP is also very useful to ensure you don't have a drive pressure issue. I do use the EGT sensors to keep an eye on my Fast Intentions exhaust manifolds for a restriction. If EGT's start spiking in the higher RPM's I know that the exhaust manifolds are starting to become a restriction. You need to know the normal baseline of what the EGT's are at 7500-8000 rpm in your lower boost settings to able to determine when you start to hit a bottle neck.

Drive pressure= From the cylinder head to the turbine of the turbo.
Back Pressure = From the outlet of the turbo, out the exhaust.

Isn't what you are talking about mostly a testing set up/tuning issue?
Once the exhaust manifold and turbo has been selected, won't the drive pressure be the same for the same engine operating conditions?

I would like to know the absolute exhaust pressure before and after my catalytic converter, but not enough to drill holes and weld bungs in my Stillen exhaust

No, it won't always be the same. Turbo cars can add boost easy. You need the sensors to tell you when you are getting close to a limit and to stop before you hurt your engine. IF you spend a little more money on the front end, it will save you money over the long run. Less mistakes causing engine damage. I should have gone to a standalone back in 2020 after I had issues with my first engine.
