I would have thought so but seeing as fitting it would mean you do have to take it easy, why not just wait until mapping? 10s seem to not like having the afr messed with without mapping so I personally wouldn't fiddle with it though
I fitted mine just a few days before mapping and I made sure I drove it off boost. I'm glad I did as 1st run on the dyno gave a huge boost spike so be careful. 10's are very sensitive to MAF changes. Hope this helps.
