PSE ISSUE !!! This can be serious
inside the exchaust there are 2 small flaps(i dont know if this is the correct word) that when you do the modification for the PSE to be all the time on, the flaps are really left free without control pressure..
This CAN cause after some time, ITS NOT CERTAIN THAT IT WILL CAUSE, a malfunction in the flaps, and after some time there might be a sound from the inside of the exhaust coming from the flaps.
this will result it a continuous annoying sound that it will not be repairable so you will have to replace the PSE.
the free release of the flaps due to the disconection of the PSE, will make the flaps go like nuts producing a disturbing sound
i hope i explained well, and further more i hope this is not true...
BUT if it is???
