For me, the pedal/tuning box are "off record" tunes, for the people who, as you said, wants to stay stock, but enjoys "something else". I'm not sure about a ECU tune plus a pedalbox, seams a bit irrelevant given that if you remap one thing that you will upgrade is throttle response, however would like to know someone that has done it and kept the pedalbox.
Yeah that is my understanding also, so if I was to buy a DTUK Pedalbox and TuningBox, I can have the benefits and remove it at any point I need to (return to stock) without ECU traces.
Just wanted to confirm that, because I read somewhere that people with Stage 1 Tunes have kept their pedalboxes, so wondering why that's all.
