Hello all. I purchased a '13 TDi last week. The car is pretty basic, though it has the DSG transmission and about 39k on the clock.

I bought it mainly for the mileage it gets. I'll be commuting over 100 miles per day, 5 to 6 days per week.

I've been looking at tuning options, mainly for the extra power and fuel efficiency upgrades that I have read about. How much truth to this and how reliable is it? My car is a CPO car so it carries a 2/24 warranty and will tuning be visible to dealers if I reflash it back?

Has anyone done LED upgrades to the lighting and what specific bulbs were used? Any radio upgrade notes? I'm up in the air about this but am strongly considering it.

Beyond window tinting, I plan on putting about a grand towards the upgrades to the powertrain at the most...what is the best route to go?

Thanks all!
