Hey Deano... In your CAPA flash box you should have a 95RON tune, which won't be as aggresive a tune as the 98RON tune, maybe it would be a good idea to load that tune in until you can get it to them... Are you a member of the Nizpro Forum? If not, then maybe it's also worth joining there and posting the problem asking for their advice directly... Good luck with it mate! Jack
