Anyone used TDI tuning box on A5 2.0 Quattro 177?

[Andrew Gibson]

Hello all, just bought a 2014 A5 2.0 TDI Quattro 177, I would prefer the tuning box stage 1 to a remap because its not overwriting my cars ECU, just intercepting/overriding instead (and it’s untraceable/removeable) and I was just wondering if anyone else has used one and are the gains as good as they say? As well at noticeable? Up to 230bhp seems really good gains along with the torque, as it would be nice to be on par with the 2L petrol. Thank you

Personal experience - I'd avoid tuning boxes and go for a custom remap always.

They rarely increase the BHP to the levels they claim and often cause issues with extended use.

Darkside Developments did a video recently on this, I'd have a watch.
