MBC on V70 T5 2001

[Soulboy]

As the title suggests, fitted one of these yesterday with strange results.

Got it boosting 16 psi, but it immediately drops to 6psi and stays there.

Take the MBC off and it goes back to 10psi solid

Would this be the actuator set at 6psi? Or do you think I plumbed it in wrong?(cos you get no instructions strangely)

Ideally it will get remapped but don't have spare funds right now and wanted some cheap horses lol, any help appreciated, tia

Because you have a me7, they dont like a mbc or a dump vale , if you keep the mbc in you would see a engine light.

ME7 = No MBC

Is that because the ECU recognises over boosting and will shut it down essentially?

Thx guys, that explains everything.

Time to save for a remap methinks!

When i stuck one on my silver p2 i had, it through a engine light and code, code was the car had detected more boost/ turbo pressure lol so pritty good

You need to remap it for one so kind of pointless.

The ecu recognises the extra load and reduces torque basically.

Another point to consider is fuelling, the stock maps are quite lean.
