Was messing with it on the freeway last night, it's not so much that mine 'goes away' under more throttle, it's covered up by the increased noise and throttle-off results in a decreased speed such that the noise doesn't occur anymore.
I think you're fine.

Thanks for the reply but I really think it's coming from the hpfp, I can control the noise with light throttle on and off at speeds 67mph and up. Just wondering if anyone else has heard it, I'm taking it into the dealer next but but I'm taking it on a trip this weekend. If it is the pump I should not have any issues since I have not heard of any of them failing yet just the noise issues, if it's not the pump I don't want to cause any progressive damage.
