The 3rd gear pull shows perfectly flat fuel pressure and this is a sustained commanded boost of 14 psi from 2700rpm to redline. And in the multi gear pull fuel pressure is basically unaffected even with boost spikes of 16.77 psi....And some of the very small dipping that you see is not due to too much boost or the fuel system being pushed but rather from the increased fuel demand and how quickly the boost is ramping...I've seen the stock tune do this..I've said this before but the fuel system stock is pretty strong but hates to be ramped onWhen you get boost spikes the fuel system has a hard time keeping up due to reaction time and not due to flow limitations..Control the spike then you can control the pressure dip....With in reason or barring a mechanical problem.ALso this was in 50 degree temps with IAT's being lower than 100 so I thought this looked decent.

I'm still calling the fuel pressure perfect...The ramping of the boost will cause a small dip but I won't say due to fuel flow limitations....I've seen it in stock logs...I could use more fuel pressure to help but I don't see the need for that when pressure only dips to 1850 psi for less than a second.

I went to guages selected Gas Ford 08 and newer and no OAR to select .. well I guess I have to plug in laptop to view these things ...
