I’ve got the same problem . I’ve changed plugs, coils,turbo, cat, manifold gasket ,fuel filter the fuel pump and injectors we’re supposed to be fine too . It runs really rich in fuel is all I’ve got . So a retune is next at a tuner.
Hey all just brought a g6et and I’m new to turbos. What parts are in a stage 1 upgrade ? Can I buy it off the net and then get it tuned? Thanks in advance
