mech5107 Posted July 26, 2014 Share Posted July 26, 2014 There is not such thing as average fuel pressure. Actually if there was it would be less than 3 bar.At idle, with stock pressure regulator, with vacuum line connected is ~2.4 bar. On boost should go to 3bar + your boost level.So your pressure is too high (4.5bar on frp) or it reads wrong. Your gauge is wrong for sure, as the injectors can't hold 8 bar...
