Throttle response can easily be changed with a tune. Was hoping for a lower price so I could perform some Vbox testing and see if any time was taken off 0-60 or 40-80 etc.The gains may be higher on the sport. The hp numbers posted by BBK are for the mustang. It may be very similar but I feel it would help her breath better. Agreeing that we really need a tune + intake + exhaust to see some real numbers. I'm interested in it because I'm doing a tune shortly and would like to have it included to see if it makes a bigger impact on the throttle response.
