Mick was kind enough to give me another drive of his car this afternoon with the final tune.
All the initial impressions hold true. It drives beautifully everywhere and keeps delivering right through to redline. It still feels like the GTX wheel is a bit less punchy between 3,000 - 4,000rpm compared to my GT3076. This is bum dyno opinion only. Mick's car feels much quicker and more lively everywhere since going E85.
I thought I should break the good news before Mick gets around to it. Mick has decided that he is going to make a merge collector twin scroll manifold to see if he can make the bottom end even stronger.
Good on ya Mick you champion.
