Just for information, I have had a Bluespark tuning box fitted to a 1.2TSI for 6+ years. I did not want to remap my car during warranty for obvious reasons but I knew a remap would be the better option overall.
My car was one of the last special offer types that came with only the 63kw option unlike the test drive 105 BHP car.
Never had an issue and it makes the car so much more flexible with the extra bit of low down torque.
I don’t thrash it or use the engine as a boy racer might.
I did think I might get a proper remap but I now do not see the point as it makes the car suit my driving style.
I told my insurance company and it only added £20 to my premium so not a big deal.
I can of course Remove it if I sell the dog kennel and sell the box on eBay and recoup a few quid no doubt, or ask Bluespark to program it to suit my next vehicle should I be inclined, unless of course I go all electric.
So, not advocating anyone getting one or the other, just giving my own reasons and experience with a tuning box.
