he gear knob should have been changed under warranty for one like mine with the chrome ring on it and apparently make a big difference , my gear change is ok not notchy not amazing but not bad if that makes sense

the part number for the new part is 30050122-asa
I changed mine as my gaiter had a blue mark on it I still have in a box as was going to sell on ebay for £40

the gear knob changes by putting the square surround up (it unclips) then peeling the gaitor up and over the knob this reveals a metal securing clamp , bend the metal so it releases and the knob gaiter and plastic trim lift off

the new parts replaces all and is about £90

the tuning box makes a word of difference to the power

the bad points are

certain settings can make the idle lumpy , the cruise will work but if you are cruising at say about 2k it surges the power delivery as I guess the car is getting more power than the cruise was expecting

the box can make the car argue with stability and traction (makes sense really) and the power delivery is far better with these disabled

I run mine on setting 7 and it drives like a different car, and is much faster, (leaves my 190 standing) but I suggest you make sure yours has the throttle map update applied from the dealer , this alters the power delivery of the 6 as standard and helps with the idle
