Hi Guys,

When I accelerate very fast she starts to jerk really hard
In the beginning we thought it could be because of the older turbo design but the guy I met yesterday told me his Legacy GT (same as mine) accelerated smoothly and he even didn't know what I was talking about.
So now I'm thinking there might be a fuel issue (pump, filter, injectors or something like that).
I really need to address this issue as I don't want to ruin the engine after we replaced HGs etc.

Has anybody ever had this sort of problems or has anyone an idea?
