I have a very poor torque while under 1800rpm, after that performance gets better. I´m thinking it could be N75, but there is no MOO sound after turning engine off. Is that always a symptom?
That's usually the symptom of the N75 gone but you should check the hoses around it also. A perished hose is a lot cheaper than a new unit. Fyi you probably already know but poor torque could be a no. of issues. Have you checked for codes?
