car running very rich....?
I took my wifes vette to the dyno this weekend. Completely stock, just wanted to get some good baseline numbers for the future. I did 3 pulls with a A/F readings. Only on the last pull did the A/F come into the scale of the dyno after acceleration. during idle it looks good, but as soon as you get on the gas, it goes way rich. 
So rich you can smell it bad. Any sugestions on possible causes. The guys at the dyno said it just needs to be driven harder. OK I'm up for that, but is there anything else I need to look for? 
TIA
Jeff

Does your wife's vette have any mods? Kinda weird that a stock A4 vette would run that rich. Your numbers seem a bit high for a stock A4 as well. Mine did 289 rwhp stock. Did you buy it new or used?
