Installed a Manual Boost Controller to my wifes car to give it a bit more oooommmphh. (along with boost guage)

Anyway, there is a slight issue. When you accelerate hard the boost gets to 0.6 bar and then stops there (making the car judder) and the goes upto the set boost of 0.8 bar. The cars ECU has a built in cut out at 1 bar and the maf can handle 2bar (according to others who have done this mod before)

Feels like its running out of fuel, bit weird.

The car is a 2.0i Turbo Peugeot/Citroen engine.

 

Any idea's?

Silly question, but you have got the pipes to & from the mbc

the right way round?

Just a thought.

think so, could try swapping it around and see what that does.
