On the topic of TIPtronic transmission upgrades and Torque Converters.
I feel that this needs to be put out there for people who have been, at little fault of their own, left to resort to blindly putting faith and money and investing so much time trying to build their Audis with sub-par Torque Converters(TC's) with less than reputable shops. I am going to leave names out of this. VAST has lost alot of time and money trying to resolve failures with TIP builds over the years, due to poor supporting hardware from these companies, whether it be a tranny, torque converter or valve body.
We're working with a local company out here in Detroit that has built TC's for cars over the years that have made twice the power and gone twice as fast as these Audi 2.7T's
Here's an exploded view of a competitor's failing torque converter.

Note the wear marks on the rivets:

another shot of some interference wear

And look at what caused it. They didn't even know how to take the converter apart in a clean fashion, so they tack welded it and it started interfering with the above piece. There's even remnants of some of the metal slag that was breaking off during operation.

Here's a closeup of the improperly modified Stator. The manner in which they did this will kill the top end fluid modulation and you'll sacrifice alot of holding capacity in those high revs. They didn't even touch the turbine. We modify that to help maintain the top end pull and achieve your increased stall.

Here's the stock paper liner that we've seen that hasn't been touched.

We've seen people advertise that they build this up. But you'd obviously think that they'd replace this if it was burnt up. This company even decided to put their stickers on the cooling holes on the back of the converter!!!! Unbelievable. We were able to test this converter before we even took it apart to see if the clutch was grabbing. We were able to spin it with very little effort. A properly working converter should NOT be able to be spun when on the bench. It's funny that these companies try and sell people on valve body upgrades to raise the line pressure to make up for their lack of quality in the TC build. If your oem paper clutch liner is in good shape, we can still build the performance converter for most applications, otherwise we reline the converter with a thicker, higher friction material. This is our "Stage 2 version". Our Stage 1 uses the oem paper filter and we rebalance it, increase the holding power by properly modifying the turbine and rebalance it all when its done.
Both are offered with a one-year warranty, no questions asked. We challenge you to try and break our Stage 2 version.

Don't forget that you have an awesome tip chip that kicks Giac....
I have one for my stage III allroad that's a night and days difference to GIAC in feel and function! GO VAST!
