this is not a flame by any means, but i'm very surprised at how much variance there is in 4.6's. my first 99 gt was 219hp/269tq, stock down to the paper filter. not too impressive. my current 99, a 35th anniversary, put up 237hp/280tq with only a k&n filter. both 5 speeds, both on dynojets.
is there that much variance in cars, or dyno's? or BOTH??
