Opel TD: Questions & Answers / Help Needed

Hello!

Okay, here's the translation:

'Just a question about an Opel Astra 2.0 TD with 86 horsepower, engine code X20TDE.'

Is there a type of VP37 valve installed there that can be modified with a 10C tuning to allow for more airflow, or does that not work in this application?

Thank you in advance to the Opel experts.

Greetings.

Sure, that's possible. What is the manufacturer of the mass airflow sensor?

Hi!

Thanks for the reply. I didn't have much time before, but I've now found out that it's a Bosch mass airflow sensor. Does anyone have any ideas?

Thank you.
