I would stick Vpower in for any of upgrades particulary 185. After that the you can use whatever you want, makes little difference, mine loves Fuelsave, and on it most of the time. ST was set up on BP95.
165 pops a fair bit but it's nice and discreet, 185 pops more and does it on upshifts, really funny, sort of chuckles for quite a few seconds. MR200 is more random, not much on upshift, but when it does it's much more of a roaring monster, come off throttle and drop a cog say up a motorway slip road and it's spits back like WRC car
