Mate the supra diff was a bit of banter, if you and Tony have issues and he wont sell you them then thats fuck all to do with me and I know fuck all about it,
If Tony wants to put the map on here and explain it then I will leave it to him,
I think my engine had problems way before the vacuum hose coming off tbh hence why I have never pursued the matter, just put it the whole EP and PE behind me and went for the best to start a fresh,
My car will be the tits mate, I have every faith in Tony
