I was wondering if you have checked any of this on your end.But basically I was wondering how the heck it is possible to make more power with less fuel pressure with the 2 on? It just seems weird. I do like the throttle response boost with the 2 stacked,and also a little better fuel economy. Your thoughts On your set up would be great.
Remember that when monitoring Rail Pressure on a truck with a pressure box, the factory rail pressure readings will almost always be wrong. The pressure box feeds the ECM a lower rail pressure reading than actual, thus causing the ECM to increase the pulse width to deliver X Fuel. So readings taken for rail pressure will be inaccurate unless done with a mechanical gauge. So, although the ECM is showing 24,000 PSI, the rail may be closer to 31,000 PSI.
