I did a search, but couldn't find anything specifically related to this topic.
What I'm interested in is "eyes wide open" view of getting tuning done, specifically on a 2.0, 170bhp, TDI A3 engine, and by "eyes wide open", I mean what I should be aware of with regards to potential improvements, but also the negatives.
Examples I can think of are:
- Improved efficiency (when not floored everywhere)
- Fun factor
- Long term impact on turbos, gearboxes (S-Tronic in my case), and possibly engine wear
- DPF issues (mine has a DPF - I've heard tuning boxes can make them more smokey, but the DPF should sort this, and I do mainly motorway work)
Cost and insurance isn't an issue (I can afford both - already checked), and I also understand how the car is driven will be a contributory factor - thrash it everywhere, and things will wear out very quickly.
So what is the considered opinion in all of this - I know people will have had tuning on cars for 40K miles, and that's good, however I do 20-25K a year and plan on keeping the car for 5 years minimum, hence I'll be racking up the mileage, although 100K miles is nothing for modern cars.
I hope I've explained my thoughts clearly, so what say you?
