Lean issues on the APR 93
I'm thinking about getting the APR 93, but I've heard that some people get a warning that the engine is running lean. Does anyone have information about this issue or know about it? I'm really hotly debated whether to get the ECU tune. I really don't want to cause all kinds of headaches and problems with my 2006 A4 2.0T that is working perfectly fine.

I am far from an expert, but I believe it is simply because the ECU is requesting more fuel that the stock pump cannot provide. I don't think that there is any real need to worry, and you can always upgrade to an HPFP anyway.
