I have a 140 DSG T6 with a DTUK tuning box that you obviously wouldn’t won’t but I also have the pedal box. This has 4 settings from off to super sport Also in each mode setting you have go +4 and -4 to fine tune each setting
And this is all done from a controller you fit to the dash or wherever you won’t.
I have never towed before so don’t have much to compare it to but I use city-1 mode around the doors and sport -2 for towing and I can definitely feel the difference as it removes the delay in when accelerating . You would have to contact DTUK and then make your own mind up I think it’s £199 and simple to fit you just disconnect the throttle wire from the pedal and fit this as a loop in and out.
Hope this helps you and is a option but like I say I haven’t towed before but this definitely makes a difference in my opinion even on day to day driving to motorway driving.
