yea the place that installed software did the up date also and the cel light came on after 220 miles..so i dont know if i am just going to get the dansk hi flow cats and extend both sets of o2 sensors back there or just live with the cel light..the cats are like 1200 bucks plus install...and there is not that big of a horsepower gain by adding the cats.. so i still dont know..thanks for the idea though..
