Joe,
I sent my MV Autos shift kit up to Andy for him to 'play' with. He said that there is no gasket in it any more and that he didnt want to split it open to find out what they have done to it.
Dean is now sending me the kit back with Andy's mod kit as well and I will be fitting both and running tests on it to see if there is a difference.
I have an acelorometer and will be using that to time 0-60 and quarters with no mods, then with Andys mod, then with MV's mod.
I think I will stay with MV's mod, not because it will be any better or not, but simply cos I spent £300 on it! And if I sold it I wouldnt feel right selling it to someone knowing there was a mod out there just as good for a fiver.
