i'm planning on upgrading my fuel system this weekend but jeff lucius has pointed out the vast electrical difference and this has raised some concern for me. does anyone out there know if there is a company that makes higher flowing injectors than the stock 220cc that have a low resistance? are all the injectors that go into the tt (i.e. upgrades, 450cc etc) low resistance? how much of a concern is this? please excuse my ignorance, i'm trying to understand this one thanks, safe travels.
