Default Throttle dead space on uprev/ecutek

I have been tuned with both programs. With different throttle maps and etc. One thing that I found has not been able to be eliminated is the throttle lag. It is easily felt if the car is idling and you slowly press the foot on accel pedal and see how long it takes before RPMs start rising. I can press the pedal good 5mm before the RPMs respond. Once pressed past this point the rest of the pedal travel is tunable with both softwares, but for the first 5mm or so it's a dead pedal.

For those who looked at your voltages of THR (Throttle position sensor) and ACCL (Accel Pedal sensor). In my case, (idling values might be different for others) when idling the values of THR are 0.62V and ACCL are 0.70-0.71 V. The THR value will stay 0.62V until the voltage on the ACCL goes above about 0.90V. This means that there is about 0.2V of dead pedal space.

Also, has anyone been able to get rid of throttle bump after pressing the clutch in while accelerating (even slow)? It slows the RPM drop between shifts, very annoying when shifting quicker.

Has anyone been able to get rid of these gimmicks? People say great pedal response after tuning, but I feel like this initial dead space is never discussed and not sure if the throttle bump is possible to turn off.
