Fist of all the car is my03 wrx vf35 sti intercooler etc I have been having boost issues and have narrowed these down to the boost control solenoid and would like to know if I can just swap this out without doing any more mapping any advice welcome thanks

 

If you swap it for the same type e.g. a 2-port for a 2-port... 3-port for a 3-port, etc, then yes, no remap needed.

If going from a 2 to a 3, or a 3 to a 2, etc, remap required...

 

Thanks I'm pretty sure it's a 2 port and I'd just be swapping it out it when lookin for one I noticed aftermarket ones all mention a remap

 

your car is mapped for the vf35 isn't it?

 

It is mapped yes is been fine for the last 6 months it was only last week the boost died

 

Can you tell us how you have narrowed the explanation for this problem down to the solenoid?

 

With the solenoid disconnected the car is getting plenty boost also all hoses also been checked this was done on a rolling road yesterday
