John as I suspected the ECU has an algorithm to prevent the engine from overload.
I removed the 220mm pulley and installed the original 185mm one then I tested the car with that phone app PerfExpert. Here's the result
Here's a test with the 220mm pulley
So I can safely say that we need either a VERY GOOD tuner that knows our cars (too hard to find) or a GOOD piggy-back system that can emulate expected ECU values.
Otherwise it's worthless to throw money and time on upgrades.
In my opinion the optimum would be bigger crank pulley, 4 bar FPR and colder plugs. No remaps.
