im bit scared to transition to 5w50 because im pushing constantly the car and nor sure if i blow the rings with much viscosity and to transition to w50 there were discussion that you should do it with a lot of km driven and shot by shot, nor sure how did you transition to w50, straight away or?

viscosity moves heat
because i don't put that many miles on the car, i just swapped the oil from 5w40 to 5w50. This is my second oil change with 5w50 and I haven't had an issues so far.
No temperature spikes and with solenoid removed gets to temperature pretty quickly, and no issues with cold start either.
I've tracked the car a few times now as well.

Your cooled pistons don't burn oil in ring grooves. Clean rings seal combustion equally. Not just viscous seal alone!
Removed pistons heat no longer accumulate to vaporize black oil on intake valves. This nearly doesn't matter when compared to unbalanced cylinders pressure.

- Strong smooth torque control ??
- Edgy lean under 1500.Rpm
- Heavy under 3k.Rpm ?
No point in rushing unbalanced cylinders.
The engine does put out high power but on few hard working cyls.
Give it some time until 3kR. vibrations level comes down towards your satisfaction
