Puma speed and jamsport from what I've read use DNA maps, would not use mountune as I don't use any of their hardware and jwr have had people switch from there maps to revo, revo maps apparently kill piston ring landings so who do you chose really.
A owner of a FRS mk2 who posted further up on this thread had no end of bother after taking his car to them and in the end gave up washing his hands of them and went to SCC then he was happy, he was not chasing numbers either just wanted the car to perform better
