Another update: still running lean and overboosting at times to 24psi with BM off>>

I've changed both hoses to the FPR and combi valve to silicone hoses but my partial throttle reading for black 32 still hangs around -7.5%. I'm suspecting this is a result of the overboosting causing it to run lean. I'm running out of options now as to what I can do. Already replaced N75, MAF, and temp sender; also isolated the wastegate actuator hose and tested it for leaks. I'm planning to have my ECU re-flashed just as a precaution. Other than that, I'm all out of ideas. Maybe I'll be the first on the forum to get one of these: <img src="http://www.forgemotorsport.com/images/products/FMACVAG01.jpg">

post your group 2 logs, I'm curious to see what your injection time is.

I noticed that my AVG. Inj. Period is different from what others have been showing. That coupled with my new starting issue which takes place if I don't drive the car for a few days and the fact that my fuel gauge acted up recently leads me to believe that my fuel system may have a problem (sender/filter/pump - either one). I wonder if your Avg. inj. period log is similar to mine. BTW, your block 32 reading shows you running rich not lean which is strange considering your post documenting your O2 and plug color.

I'm getting the ECU re-flashed tomorrow morning>>

I'll get some logs for you after that. As for the block 32 readings, I thought the same thing as you too, but Steve corrected me on that one.<ul><li><a href="https://forums.audiworld.com/tt/msgs/1668012.phtml">Mr. Schwing's reply</a></li></ul>
