md321 t high boost low rpm issues
Got md321t and have an issue with motorway in gear acceleration with high boost at low rpm.
This causes an annoying judder through the engine/turbo.
Can anyone explain this and offer some sort of solution.

i did think this may be generic problem associated with any turbo application, but here is my spec:-
04 sti
ceramic coated md321t
3" miltek with sports cat
650 flow matched injectors
reversed inlet manifold/hyperflow front mount
gt spec ceramic coated headers
prf7 plugs
walpro 255lph fuel pump.
tial dump valve
ecutek re-map
main problem is in gear increase in speed at motorway speeds (5th/6th) at 1.4 bar. i don't want the only solution to be change down a gear.
I understand it may be compressor surge, thought someone may have a solution or be able to explain what is going on to cause it.
