Hi All. I've picked up a 2005 C5 allroad with 24,000 miles on the clock and it's in pretty much mint condition. It's a 2.5 TDI Tiptronic and with so few miles i think the engine/gearbox should be able to handle a little more power. I've always understood that a remap is the best option for cars over a tuning box, however for these engines there seem to be some opinions that suggest otherwise. What is the general consensus re: remap vs. tuning box and if tuning box is the best option what should I go for? Many thanks!
