I was wondering what kind of stuff you can do with the wastegate. I am sort of clueless on turbos and i always hear people saying stuff about messing with the wastegate. what exactly does it do and what can you do to it?

pressure builds in the wastegate and will create boost. a spring inside the wastegate will hold that pressure up to a point, and then release it, creating the turbo power. the stronger the spring rate, the more boost, the more power. But also lag. Can't have'em all

Alright, the wastegate is a little valve that opens at a set boost to let exhaust gases bypass the turbo. What people mean (on this site at least) by messing with the wastegate is that they've changed what boost level the wastegate opens at, so that the turbo builds more boost before the gasses start to bypass. It's really a pointless mod though (as has been pointed out) because the car's computers adjust accordingly for the changes, thus putting you more or less back at square one. Running an MBC to bring boost on sooner is probably better, IF YOU ARE SUFFICIENTLY CAREFUL.

What I meant :D I'm just lazy and writing a paper.
