We all see a lot of posts about ECU/TCU upgrade options and I personally would like to see as much feedback from RS6 owners about personal experience and feedback both positive and negative in real-world environments. If this was all located in one place or in an FAQ somewhere that would be a great asset to us all.
Can we set up an open thread about MTM, GIAC, Revo, O.TC, APR (any I am missing)? Perhaps an open invitation to owners to provide feedback on the chip they have installed with any performance numbers (Dynos, seat of the pants), manufacturer support, malfunctions etc?
Here is a copy of a reply post I made in another thread:
Hmm, I don't have any reference point on APR. The ability to change the programs is appealing since I also use this as my business ride and want to conserve fuel for long distance trips around the Southeast and also have a nice smooth feel when clients are riding in the car with me. I heard that the ECU/TCU upgrades make throttle response a bit touchy. Is that the case with O.TC?
APR wants $2800+ installation. I was going to drive to Auburn, AL and have the factory install it thinking they know best and it is only about a 3 hour drive from Atlanta.
Maybe I should reconsider this. I can't seem to get an exact read on MTM vs. GIAC vs. O.TC (forgot about that one actually) vs. APR
APR has the features I want and are (sort of) in my backyard, so I was thinking of this direction.
Any APR peeps have info? Maybe a separate post is needed. I'll copy this and start a new topic.
Thanks!
