What would one have to do to get the tranny to handle the extra torque? Is it possible to do this w/o having to buy a S6/RS6 tranny?

Just thinking out loud...

ok, you have mail!

conventional KO4 applications. Means you won't launch much faster, but as soon as the revs climb, you'll be picking up speed very quickly.

Marc at AMS has been toying with the idea for a while now. He's about to install a 4WD MAHA dyno at the new shop.

I realize that they have nowhere near the resources of a manufacturer, so they cannot generate much in the way of bare engine dyno results or in-depth analysis of torque-at-the-crank at a given RPM; and they certainly cannot run the long-term test on engine/transmission combinations to determine longevity.

However, given that these chips probably void one's warranty, and the chip makers probably say this in bold print, why don't they produce a broader range of upgrades for the faint of heart? I'd love a chip that did nothing more than boost HP at the 4-5000RPM level, without putting torque over 300 lb/ft. It's all software, right?

There's no need to go to K04s for that.

Let's face it, many chippers are young and looking for the largest number and the sharpest kick in the back. Their tuning experience isn't very sophisticated. The tuners are happy to oblige becuase it isn't very hard to make a snappy chip and claim big numbers - awd dynos being rare and expensive. If you don't play that game, you aren't fashionable in chipper circles

I know that AMS consults a great deal with Abt as well as AoA. If AoA says "don't go there" AMS won't. They get a lot of custom requests, but very few folks are prepared to do the development to make it work well and test for some indications of reliability.

The main limiting factor with the KO3, is that high rpm boost is limited by design. That turbo does best a low to mid range.

Shows that AMS is a least looking in that direction.
The good thing about going to a K04 Type design would be you can run less boost and achieve good results. THey are more efficient. Less pressure means lower temperatures. THe K04 will be well withing its operating range where a K03 is stretched at the high end. I think K03 is rated to 1.3 bar??? not sure about that. SO if you spiking at 1.3 or 1.4 you are taxing those little K03's
Bad thing is, more turbo lag, trading off some quickness for being faster at the top end. YOu would see 0-60mph times fall off, but 60-120mph you would see a big improvement.
A K04 for the tip would most likely use stock settings, what I mean is fuel and such. They probably dont change the injectors and stay with stock downpipes. You still have the tranny to consider in all this! : )
So I guess its a detuned K04 type application to suit the Tiptronic car with the turbos maybe hainv better reliability than the smaller K03's.

Come to think of it, I guess you could just put in the K04s and run the same chip/software. If I remember correctly, when LCP put K04s in his S4, he ran the stock ECU for a while with no problems. Should work the same with a chipped ECU, no? Would be nice if there was a way to 'upgrade' the tip tranny (for a reasonable cost) to handle 400+ft-lbs!
