It’s widely accepted that tuning is a key way to boost 3.0 TDI engine performance, but I’m curious about how tuning approaches differ between Gen1 and Gen2 engines. I own a 2010 Gen1 model and a friend has a 2015 Gen2, and we’ve noticed varied results when applying similar tuning principles. Have any of you noticed significant differences in what needs to be adjusted or how the engines react? I’m especially interested in whether the newer Gen2 models require less aggressive tuning or respond better to certain mods. Also, are there common pitfalls people face when tuning across these two generations? Any insights based on practical experiences would be appreciated as I’m considering a tune next.
