According to the local tuner up our way (Star), the GIAC unit does not up the CPU flash counter which effectively means that provided the car goes in to the Stealer as standard after switching the programme using the box provided, there is no way they could ever tell the car has been touched.
Without bumming up Star (I doubt I will be going back to them) my old switchable Star remap was never picked up by the Stealer and it was in for warranty work several times and SEAT technicians both from the Garage and SEAT UK never detected it, and the flash counter must have been to at least 50.
As said previously, I dont think I am alone in thinking this but with the
MK2 Leon being so new, a switchable remap can only be a good thing as it is way to obvious if a turbo car goes in to a stealer remapped. At that point, no doubt any
problem could be attributed to extra power if the Stealer wanted to get s****y.
