Really? May have to do with your Revo settings, highest I have seen on a hot day is 22psi, normally in this cooler weather I peak just shy of 20 and hold 18.
Yeah man I have no idea. I spike 24-26psi (determined via boost gauge), and hold at 17-18 for quite some time. I have this massive rush of boost and torque in the mid-range, hence my slipping clutch.
I have no complaints as of yet. The car pulls like a demon, and doesn't seem to be doing any premature damage from what I can tell. The key is preventative maintenance.

Damn!!!! I'm thinking about switching to Revo.

Boost Pressure does not equal Power. Not to mention the variances in boost gauges.

I guess you're right, and I still gotta get the gti dyno-ed to see where I'm at w/ APR S2.

x infinity.... vagcom gets real boost and I'm almost sure its not 24-26 I think were limited to 23 iirc .

I have a different theory on the cold weather idea. My clutch was just replaced and I was slipping more in the cold, but I was slipping in the warm too. It's way worse with a car full of people too.
I definitely feel your pain guys. FSI here, but the problem is the same.
I hear what everyone's saying about sliping because of the friction material somehow shrinking and retracting.
but...
I disagree with this theory though.
One second of slip and that friction disc has to be hot as hell, just due to the friction created by the slipping itself (think rubbing your hands together at 3000rpm), not to mention the heat of the flywheel, which is directly connected to the crank, which is immersed in hot oil. So, if the disc was cold, due to the ambient temperature, it's not going to be cold after just a few shifts of the transmission.
I think the real reason we're slipping more in cold weather than in warmer is timing advance and cooler air intake temps. When your intercooler is being cooled with 30 degree air, it's going to cool your intake charge temps considerably when compared to 60 degree ambient temps. Our cars' computers then are able to advance spark timing, thus making more torque. The cooler air alone will also increase torque as it is more dense than warm air (more oxygen per volume).
So yeah, I blame the increased slip in the cold on the car making more power than it does in the warm.
My 2 cent theory anyway.
Not that this helps the fact that our clutches aren't made for 50% more torque than stock. Can't blame anyone here though. You gotta pay to play.

im gonna go with an oem replacement with a sachs stg3 clutch plate.
400whp clamping power, and its a couple hundred $$ cheaper then a SB kit.

Sounds like a terrible idea to me... without a stronger pressure plate I don't see how this would make any worthwhile difference.

I wasn't recommending it, I just came across it and thought I should share. I don't know much about clutches, what could be the difference without a stronger pressure plate?
