Sounds like you already have a map, lucky you
Get it validated on the RR. I would also see if you can contact a Revo dealer and have them identify if it is indeed a revo map. If so I think it's only £50 for the SPS which will then give you the flexibility to swap between standard and remap.
I'm still not overly convinced that my old FR hadn't been remapped as since buying the
K1 ive noticed little difference in performance and dare I say it the FR felt quicker! (possibly due to the DSG and the higher revving low done of the smaller turbo may have made it sound quicker!)
btw my dealer never commented on the FR being mapped when it was serviced but they may not check (or care!)
FYI, there was a thread a few weeks back about whether remaps affect warranty or not as some stealers are actually revo installers! The question still up in the air!
Good luck with RR and the extra cash you may now have for other mods
Also good on superchips for letting you know. I don't buy the fact they can't reset to standard they can. But reality is you'd be looking for extra performance and you wouldnt notice it given already mapped, I think that's their major concern
