Power chips for cobras
 

I recently traded a '00 GT for an '01 cobra convertible. The book says the Cobra has 320hp and the GT had 260hp. I can't tell a big difference in pull between the two. Is there a reason for this and, if so, will a power chip help get my hp up?


p.s. I just upgraded to a K&N air filter and housing but everything else is stock.
