You need to block off where the N75 was fitted to the TB pipe then the then you have two pipes left which you must have the wrong way round or you have not set the ebc correctly.

 

I'm starting to think that my ebc is broken. even though i got it new in box. no matter what i set the duty cycle now my boost is always 12 psi. but before i did this, remember the old turbo was making 14-15psi.

i did this yesterday but instead of using a MBC i used the EBC solenoid.





I dont care if I cant raise boost past my chips specs. but with this EBC but i want to be able to lower between like 8 and 15 psi.
