Peugeot 308 GTi in for service and a stage 1 ECU tune.
I noticed the under tray was loose so sorted that out as well.
These run a Bosch MEVD17.4.4 ECU so it needs to be benched, as the Kess3 won't connect to it through the OBD port. ECU unplugged, pinned out , back up took of the stock file and then new tune wrote onto it.
