I mean, with this type of SC you don't measure the air coming to the motor with the MAF, because the SC are after the MAF, please correct me if Im wrong guys...

I think you are right, which poses the question - how does the DME know the pressure? The MAF before the SC measures only Atmospheric pressure. So actually more air goes into the cylinder. How did ESS actually tuned the engine without knowing the pressure in the inlet manifold?

It doesn't need to. It knows the amount of air drawn through the MAF meter, which is fairly close to the actual air in the manifold. At least on the MS45 there is a function which models the current air pressure given the characteristics of the intake manifold.

And what about the air temp after compression which be slightly increased (or even more for TS1 with no cooler)?
In the MS43/42 we have a separate air temp sensor in the manifold but the MS45 has its sensor in the MAF.

I am surprised the air temp sensor is not relocated. Maybe they shut off the air temp controlled spark modifier.

In my engine (ecu is m42) the sensor is relocated into the ESS manifold.
I dont know about the m45

In my opinion, does not matters where the IAT are locate, because if you have the TS SC the AIT are BEFORE the scrolls, if you look closely you will found the IAT after the throttle body but before the TS SC and obviously before the intake manifold....
in both case the IAT measure uncompressed air (IAT in MAF or IAT after throttle body and before the TS SC)....

ESS should be able to supply both 90 and 83mm pulleys. On the 104mm pulley, there is only enough material to reach 95mm comfortably.

I had considered having mine machined down, but even the engine machine shop said they can't do it. I found the 6 groove cutting tool online though. ESS wants crazy amounts of money for their pullies.

Small update:
I got the 85mm pulley from ESS and now the car is boosting 9.5 at redline. AFR is ok.
Now i need to understand why i have oil leaks from the center of the pulley, messing my engine bay and the plastic cover under the engine block (it was leaking also before the pulley change. Two days ago I checked the oil level and there was almost no oil. So i filled a new bottle of 120ml. I mailed ESS about it, maybe the center hole can be sealed of something.

you overfill the charger with oil, thats why you have oil from the center of the pulley.....

I am aware that it might leak when over filled. ESS got back to me and said will also leak if the car is tracked and my car is drifting a lot. That when i see the oil messing up the engine bay. I though it was a steering fluid leak at first.
I also lift the car to replace rear tires so it might leak when lifted.

I dont think you can seal the center hole because I think there wont be a breather left then. (and a sump without breather isnt a good idea)
Maybe you can use some kind of porous plug that blocks oil (splashes anyway) and can still breathe (like wet air filter material) or plug the hole and mount a breahter+fluid maze on the top filler hole.
