Oh no! not the stickers!
If I remember it was stickers, and the ability to get them, that started THAT thread no so long ago......you all know the one.....
Anyway, deffo go for foil backed, got some from CMW in Chchester, about £4.50 a pair for the DP ones.
For Chip I'd go for the FIM UltiMap one, it has separate mapping for each cylinder (coz one runs hotter than the other etc.)
