Thanks Dave.
I'm not sure why everyone got into Mao for, I asked him for those dyno graphs personally just for my own records.
Anyway, Sean got into my car today for his turn at trying to tune it. I think he forgot to put my initial run in as we did it about two weeks ago so i'll have to try and hunt that down, but I have dyno results below for today's tune.
He told me to come back in about a month or so when there's an update in the software. He wanted to increase my boost slightly to make a bit more power but didn't have the parameters to do so as yet. Car feels a lot more lively now so it'll keep me entertained until i take it back again.
So I guess now I can assume that it wasn't hardware in regards to the Martin Donnon tune, so I wonder what it was that made it go so wrong?
