Turns out it was the thermostat & everything was covered under warranty.

Since chipwerke controls the relief valve do you guys think that APR pulley can be a great addition since the pressire will build up faster. So more power at lower RPM?

Haven't been on AW in awhile but this Chipwerke piggyback mod looks like a cheap way to squeeze out some extra fun power. Been enjoying my A6 for almost 2 years with very little issues.

I believe it will work, but that kinda kills the point of it. The great part about a piggyback is that you can quickly pull it off for dealer visits. If you swap the pulley, thats not coming off without major work.

Just so you know, a TMAP tune like this does NOT control the bypass valve. I suppose you could say it does "indirectly" because a tune like this simply tricks the computer into thinking not enough boost is being made so the bypass valve doesn't open as much thus creating more boost.

A tune like APR or GIAC does have direct control over the bypass valve (I understand this to be the case) and that is why those tunes don't drop off so hard above 5000rpm.

Also, a pulley would do nothing for this tune other than to spin the supercharger quicker and force the bypass valve to open sooner. APR can control the valve and when you run a pulley they can spin the blower quicker to make more boost.

FYI...

I've enjoyed my chipwerke for a couple of months and have put it to use posting respectable autocross and track times.
Yesterday while driving on regular roads I had an orange check engine light come on. I pulled a couple of engine codes. I didn't save the exact number but one was regarding the boost and the other was the MAP and throttle position. I disconnected the piggyback, cleared the codes and the light went away. I'll drive it for a day or so before reconnecting to see if that was in fact culprit.
Did anyone else have a similar issue?

I haven't had any codes come up. What do you have the CW set for? If you turned it up too far, then it might cause a problem.

I haven't adjusted anything. I just threw it in. What should it be adjusted to?

Mike_L

Nothing, just leave it the way it was delivered. It can be turned up one or two notches for 93 octane, but otherwise, leave it as is.

koalaballa, how is the tuningbox going thus far are you happy with it, how is the performance on the TDI.
