^^And you should be pleased witht the result, who wouldnt be? The reason I asked the question is because I want to know what mods are needed to reach 100bhp+ on a N/A as I want to achieve the same sort of figures. Running a fuel pressure regulator will stop the car running lean bceause it increases the amount of fuel entering the mixture. But if your car is running fine without it (not lean) then i dont see the need for getting one. my 2p.
