Do you not think that tricking the ecu into thinking that the boost is different than it actually is will mean that you run the risk of causing engine damage?

No read the link in the link that you provided it explains all the stuff that it does.. It is like a boost controller.. stock... 11psi.. 17psi.. it would work..

I did read the link, thought I understood it, you "clamp" the boost at a level just before going into limp mode no?

Thought a MBC was also a no-no on a 1.8t?

A boost controller is a no no but you are doing it in a different way to which a boost controller works..

yes so if you clamp the sensor and fool the ecu you dont go into limp mode.. problem solved..

What values would you use for a mapped car?

Also, take it you would need a mbc for this?

mbc ?? manual boost controller ??

You cant run a boost controller on a 1.8t at all whether mapped or not because of it being a recirc turbo.. will cause issues..

Im not sure on a mapped car to be honest..

I don't understand, how can you increase the boost otherwise?
