hi I am having problems with my subaru impreza turbo awd 1997 UK speck it was runing standard then I put a dcat straght trough system with front mounted intercooler now my car cuts boost at 1.2 psi on the boost gadge I've upgraded my turbo to a vf34 and it just got more vilont people say to me that it needs a remap now because of the dcat what do you think

 

Yes it needs remapping mate.

 

Remap.

 

Definitely needs mapping as you've released all the back pressure and fitted a fast spooling turbo so will hit boost cut almost instantly as soon as u try and accelerate.
