Odd noise anyone else have it?

[Pkay]

Occasionaly in 3rd gear at higher rpms (when accelerating quickly) ill here a "urrrrrrrrp" sound. Very quick very faint but loud enough to know it wasnt there before.. Can barely be heard over the intake. Just wondering if anyone knows what this is?

mods on right now: injen cai, hardpipes, hks ssqv- bov/bpv setup, mbc 9psi

I think I get that sound between 3K and 4K. I'm not sure what it is though... maybe going from vac to boost... (blah) I have no idea

It's just gas, man. Lay off the chili before you leave the house.
