No idea what the ethanol % is... At the gas station when filling up the car i noticed that there is E10 written on the pistol... 1 - 1.2 bar is the turbo boost.
I have also noticed that when i ran stage 2 /before the custom tune/ around 160-170 km at full throttle the car loses power completely. I used those cleaning products which are for fuel injection system changed the spark plugs with NGK 97506 0.20” gapped and i think this problem disappeared after few hundred km.
Could it be a problem with fuel injectors or igntion coils?
