Hi, I have a VR V6 manual with an SC14 supercharger running around 7-8psi, I have a 3 bar MAP sensor too, not installed obviously.. At the moment I am running a rising rate fuel pressure reg but I'm not convinced that it is the best way of getting more fuel into the engine. After searching around on the forums, people have recommended you for a job like this. Are you able to help me? I realise that I should have got a 2 bar MAP sensor but it was all my local mechanic could get me at the time, easy enough to sell and get a 2 bar though. Anyhow please don't hesitate to contact me if you can help or if you need more details. Thanks!
