^Like he said, any tuner will add to the VP problems, a big issue is the lack of fuel moving through the pump to cool it when you add a tuner. Engine calls for more fuel, meaning its sucking it up quicker than the lift pump can supply it. You get low FP, and it is bad for the injector pump. Before ya go and invest in a new VP, get an aftermarket lift pump and a fuel pressure gauge. You are aiming to keep it above 10 psi while at wide open throttle.
