Audi A4 B9 ECU and Gearbox
I'm currently planing on getting an ECU and gearbox tune for my 2021 Audi A4 B9 mk2 35 TFSi (2.0L turbo).
The tuner says it will map quite easily to 240hp with 470Nm torque from its current 150hp.
What i'm wondering is what extra steps are needed when tuning?
Do I need better oil?
Cooling system?
I've heard that the 35 tfsi and 45 tfsi of this generation are pretty much the same engine (or exactly) so this should all still be safe within part limits and all its really doing is taking the 35 tfsi to the 45 tfsi level.
Any extra info would be really helpful!
