So my next mod after the heat exchanger was VMP Fuel Pump Booster kit for the 13-14 GT500. During the dyno tuning for the Stage 4 Power Pack Justin at VMP noticed my fuel pump duty cycle was maxing out at 5900RPM. The fuel AFR was still in an acceptable range but we knew this would have to be addressed. With the boosters we saw a significant drop in fuel pump duty cycle which gives us quite a bit more safety when pushing the car.
I'm curious if others has had issues with their stock pumps at a similar power level or if maybe my pumps were just a bit weaker than others. Either way this was a great idea that will help keep the car safe and give me a little bit more room for the longtube headers, vmp gen 3, and cams. I will be going to a fuel system later for E85 but this will work well for now!
