we actually installed one today on a near stock vehicle (had a cold air intake and SSQV). the car operated perfectly with it, pulled hard and smooth. we haven't seen any downsides to this modification thus far. we've gone with a different supplier and design for the internal pump parts since the initial launch last year and been very pleased to date.
the near universal compliments we've gotten back are better and smoother drivability, less fuel cut, more consistent pulls to redline and less hesitation. keep in mind this; the pump is not designed to increase horsepower. the pump is not designed to improve dyno results or better your track times. the pump is a complimentary modification designed to increase actual and potential fuel supply and one whose effects will be better felt by people who have done progressively more modifications and those who have tuning solutions in place.
if you have hesitation, fuel cut, power falloff, etc, the pump could address a good part of that on its own. nonetheless, the ultimate benefits will show themselves on more heavily modified cars where tuning is present.
we've heard some pretty disparaging rumors in the last few days about the pump that i want to kill right now. a competing vendor told a valued customer of mine that they had heard multiple stories this week alone of these pumps blowing up cars, washing out engines or causing fuel dilution. not one shred of this bull is remotely true. common sense would dictate that at least one of these people would have stepped forward on a forum and said that a pump blew up thier car - which they haven't. if engines had been washed out or the oil diluted by excess fuel, you would see loss of compression, seized piston rings, extreme power loss and poor idle/engine operation - again, which has not been seen. the only failures we experienced with these pumps was with the last year's batch having shoddy internals, and not one of those failures led to an engine being damaged or blown. it really angers me to know that a company would either be misinformed enough to make such remarks or outright lie to the customers about this, and i felt the need to clear the air once and for all.
to cap off, nothing else is required to install or use this pump.
