hey guys this happened a while ago on the last day before the TA went in the garage for the winter. A newer 02 SS pulls up at a light. driver says its stock except for an exhaust and its A4. Car was loud but had no cam lope to it. i let him get the jump first though. we went from about a 25 roll to 110 and i was at his back bumper the whole way couldnt pull at all. How is this possible? I know i need new bearings in the rear end bad, been about 3months like that. And the MAF is reading wrong hopefully due to over oiling kn filter. You guys think he was lying or are theese two parts hurting my cars performance that bad?
