I'm pretty sure that it controls how quick the boost comes on..

as in how much wastegate creep there is.

EG.

If your boost is set to 15 psi, normally, your wastegate starts to open before that to make the boost come on in a controlled and smooth manner and by 15psi, the wastegate is open and only allowing 15psi to be produced by the turbo.

If your controller is set to SHARP, then the wastegate will not open at all until something like 13 psi.

so up till then, all the exhaust gasses are going through the turbo and the boost comes on really strong. It's not a smooth boost delivery, it is more like a huge rush to the set boost limit..

In a rear wheel drive car, setting it to SHARP is probably not the best option cause it's just goign to fry the rear wheels.

in a 4wd car.. That could be fun..

oh thanks for the info

so say i wanna run 0.8 bar

wat do u think i should set the mild/sharp thing on?

Play around with it..

start with Mild, go for a hoon, pull over, increase it a little bit, drive again... and so on until you get to a level where you feel it responds really well without ending up in a cloud of tyre smoke..

I'd also add that more boost = more fuel consumption.

I set mine damn low as there's no point flogging it going to work or on the rain.

You basically need an open stretch of road (er ok dyno) and a co-pilot. You basically want it to rise as quickly to the boost position without having any "flat" spot (like it goes up quickly, then the reach to full boost takes ages), and also where the boost doesn't drop off when your foot is flat to the floor during redline. I find about 1/4 of the way around works best for me.

Played with it a lot, I think i've got in on the perfect position at the moment for my car.

That'll only cause spiking boost anyhow, and it won't hold your desired boost either.
