does this make sense?
At torque of the devil chris noticed that the fuel pressure was not increasing when the boost came in causing it to run lean and then misfire. My bosch 044 should supply 4.4L / min. I tested this both direct from the pump, before the fuel rail and at the return at the tank....all fine at 2+ L in 30 secs...
Fuel pressure regulator should increase the fuel pressure but it didnt...the only thing i can assume is that the regulator is at fault...agreed?

I would first double check you have no blockage, see if the reg holds vacuum when you suck on it, when you take the pipe off the reg if gone petrol will be in there, there are just two thin diaphragms sandwiched together that seperate air/fuel, but if lucky might be a bit of crap blocking the pipe, there's always hope!!
