A lot of people think you need a mondo spring at the carb, so check that. Even purpose dual return springs are pretty light springs.

IMO dicth the spring on the cable if there is one.

If all the above is good then consider adding a throttle arm that extends the radius of the throttle movement, thus providing more pedal throw per throttle opening. Just don't go so far that the pedal hits the floor prior to WOT or you won't be able to pass Testarossa's
