LLY's have e restrictive mouth piece to the turbo that most replace with and upgraded one that would be first on my list if it hasn't been done already. 2nd would be a lift pump with filters system to keep positive pressure on the fuel system as it is under a vacuum with the stock set up which is prone to air leaks causing problems with the fuel system losing prime and I wouldn't delete the stock filter but leave it there for extra filtration and retaining the water in fuel sensor operational as to warn of possible water in the fuel.
