YepSo you could just push harder on the throttle to get the same effect then.
It depends how much you want to spend really. I find with my 2010 d22 that having blocked the egr and fitted a straight through exhaust that I have great throttle response from basically idle. I get full boost about 1250rpm from memory and don't have any trouble running down to around 1000rpm when just plodding around town. Stick the boot in though and she goes pretty well for only having 98kw... Plus mine is probably up around the 2.5t mark as it sits at the moment... I really should try and weigh it again.
i see manufactures have this sort of thing built in.
power/economy mode which simply changes the responsiveness of the throttle.
a few reports of them being absolute pigs to drive when in "power mode" as it tends to be full throttle or nothing.
however some find the economy setting worth while.
the other quirk is sometimes manufacture tune it so there is a delay in throttle to give the EGR system time to react. ie reduce egr before your pour heaps of fuel in so you don't cook the pistons.
