GAS PEDAL SPRING TOO WEAK

[Al_]

It is an issue with DBW as said before but not a big one, the lag on mine is something like 1/4 of a second and the easiest way around it is to wait until your foot is off the accelerator until pressing the clutch.
If you are a slow shifter then you won't even notice it it's that small, even I only notice it when shifting it's small enough that when going from coasting to accelerating I don't notice any lag.

The light pedal is just something you will get used to as you drive more, you could try wearing shoes with thinner soles.
