...yes, that old favourite of mine when the patient is a VAG TDI - an el cheapo resistor mod 'tuning box'.
Definitely more grunt low down - cleanly accelerated up quite a steep hill near here last night from a 50mph rolling start in top.
It did this pre-tuning box, but not with quite as much urgency.
Motorway work, the computer reckons it's returning around the same as before... slightly slower single carriageway A-roading though, it's reporting back a fair bit more mpg, so all in all I'm pretty chuffed.
In fact, and I throw open the doors to the usual 'It's s**te' banter, but I'm actually pretty impressed with the car, full stop... bar maybe the brakes - they definitely feel like they could do with a bit of beefing up.
They've definitely focussed on the comfort aspect of things rather than handling when it comes to the ride / handling compromise, but it does actually go round corners if you ignore all your built in instincts to back off. ;-)
I'll be investing in some alloys next - the jury is still out on whether to get a set of vRS ones, or stick with something closer to the original 14" steels.
I'm getting old... I like my main runabout to be more comfort focussed than track spec. ;-)
