Yes, you should, Mark.

I should have listened to you the day I picked it up. As is often said on here "pick a tuner and follow what they say". It is bonkers now, I gave it about 80% today as a merc was up my arse and I was shocked at how I left him so far behind. I looked at the log after and I just caught 6000 rpm so there was more to go and it felt abnormal. I have yet to give it full bore gear after gear. It seems super bike quick to me but near 500bhp and 1000kg should I suppose.

Carbon fibre tailgate is about to be ordered, that is another 20kg gone
