I mean I never tired to use BP fuel on dyno, i've tired Shell only, and what i mean about the dyno is, "I don't trust the numbers at all", my car got slower on the road after tune

anyway, the weather is quite cool when i did the dyno, BS GIII, same dyno(See ann Jay )

PS: Although everyone said Shell gives more power, but i don't like it, i don't need "car steroids", and least it makes my car addicted to it already.....
