Loss of performance over 2.5/3 K RPM
power curve appeares to be ''n'' shaped , 3k top
Car was mapped S1 at the start of the year
Issues with boost , flutter at high rpm
one power drop during map .....suspected turbo as 180k
New oem recric valve fitted last year , new n75 about 2/3 year old [20 k miles]
Post map , fitted AE stage 1 recon turbo [enhanced bearings , seals std control ]
Ran fine for a while Now appear to have performance to about 3k rpm then ,
open the throttle very little happens
Worst case re-con turbo failed ?..only few 1000 miles old appears to be ok upto 3k
I see pointers to N75 and associated pipes < most likely ?
Tnx-Graham
