going to pick your head with something else if thats ok haha my car feels underboost problems no check engine light but when i scan my car i get a code p0299 underboost
changed the diverter valve put a ugraded piston gfb+ on it got a rattle from i think is the wastegate rod or he wastegate inside the turbo does this mean the turbo is bad and will need replacing
been reading n75 boost pressure control valve could be bad should i change that and see if the boost comes back
any help would be great huluis
car is APR stage 1

I also have Stage1 with the gfb+.If the rattle comes out of the turbo it could be the wastegate valve or,a friend of mine had this,is a crack in the Turbocasing,it goes from the Valve to the outside.
