Jeff,
Glad its working well for you. I never wish poor luck on anyone no matter what they chooese. That said let me ask/warn against this. Im not sure how audi ecu's are, but I know the honda (and a number of other mfg'ers) have obd II ecu's that attempt to correct to stock. Over time they will "un-do" your settings. The way around that is to reset the ecu everytime you turn the car off. In other words setup the ignition to reset the ecu with every start. Again, I am not sure if this will work on an audi ecu, but it may be something to investigate.

Im curious about your setup though. Do you have aim? Do you mind me picking your brain a little?

Thanks/Good luck,
Mark

 

yes i have aim its climbhighh. i just got a new ecu chip. it is a modified ko4 chip from apr. they had to change the boost settings around and mess with the fuel. the chip has a cool feature i can hook it up to a lap top and change some of the settings from there if needed. i will still be able to run the afc to make more precise changes along with the boost controller. if i run into any problems i can disconnect the afc and just run off the chip
