Spark plugs should be a light tan not white. You're running 7 heat range plugs, which
should help cool the combustion chamber. Can you check with the VAG the air/fuel
ratio?

I just went out and did a lot more vag logging... 3rd gear pull up to 6400 rpms, the mass air flow g/s only gets up to 150 MAX. The block 32 multi lambda value got up to the low 20's. If the front 02 sensor was not working how would I know, and wouldnt it through some errors that my vag com would detect?

I bought another MAF from Audi just to make 100% sure the problem wasnt my maf... and as I thought, the maf is not the problem. I am bringing my car in in a few days to the apr tuner in ri. I have 2 mafs for sale.. they both work... if you need one go to the classifieds
