did you rescale port injector MRP compensation table for boost?
in my case, that helped a little bit.

He did, but he won t go lower than 4 of engine load with just that
He would need to make the maf scaling in open loop about 20% lower at least and force more fuel putting a lot lower "cc" value in the port scaling table and go from it

DI scaling is a lot more complicate since it s a 3D map and it uses variable fuel pressure, I guess it could help to put out more fuel than intended while keeping less load but cannot help with that

I assure you that cable feels even cheaper than 24$
And let s not talk about the shitty delicate USB dingle that breaks just by looking, and if it happens you get an heart attack
But you will like it anyway
