Hi again. Now I need another help about my car. We do some changes on engine and now we have problem with fuel - lean mixture. We have about 200 hp and we don't know how to increase fuel. Increased fuel with back box, with ke jetronic, with bigger injectors but nothing. And now tomorrow will install 5th injector in intake. But we never do that before and need some advice. If someone can give advice about that, what to do and etc thanx brothers
