Granted I'm new to this but if you're talking pedal response in general then pedal to torque curves. You can add more columns and make more aggressive. I did just the opposite with my manual tune. I changed columns to 0, 50, 90, 100% and added all of the torque increase at the 100% column to make my pedal response feel like factory down low through 90%.

If you're looking for better response when you floor it period, then you're talking about spool time: then smaller turbo OR more fuel which taken to the limit results in black smoke which can be compensated for with nitrous.
