I know you said you didn't want to affect the warranty with a gearbox software update but I wonder whether 'they'd' notice?
I updated my 440i GC and the lag was gone. Ł100 and a much more satisfying drive.

I think something reversible is probably better like a pedal box. The DME will still pick up a manipulated signal but it doesn't look as bad as a map. In essence it's just changing the distance/travel required on the pedal (so a once inch press is like a two inch press). Where as changing software (re-write or flash) is more permanent (even if restored to oem there is a counter on how many flashes). Nothing urgent. It's back in the garage anyway since we have been told we're working from home from now on.

I experienced the exact same throttle lag some time ago when I test drove the the 430ix. Slamming on the gas pedal was followed by a hesitation of about 2-3 seconds (!)A 1.0 liter VW Polo’s automatic was more responsive. I asked the BMW dealer (Brussels, Belgium) and he said that this is how the system is set up by BMW to prevent accidents by the involuntary push of the gas pedal. So he said that the system was slow on purpose (!) I found it hard to believe that BMW would dumb down its own transmission. However, it may be true because when I used the pedals on the wheel, the shifts were super quick, so the ZF is capable of quick shifts. I've tried different settings to the engine and the transmission (sport, sport+) but the problem persisted when I wanted to accelerate hard at low revs.
