That is quite an assumption. I would have opted for a dyno run on each setting (it will lake 5mins) and then over lay the four graphs and opt for the one that looks the best, and the one that looks second best. Then road test to these two settings. The answer might not be 0.

Not an assumption - although having re-read my post I was very vague & what I should have said is 'I found he '0' setting to be best suited to my quattrini engine'...
I did have mine set-up on a dyno with the HHPv4 being ran through all 4 settings in exactly the way you've described (and re-dyno'd with each change of exhaust)... I also road tested the engine extensively, switching between the two best settings & settling on '0' as the optimum curve for my engine.

Yes very happy with mine... I went for the Bullet 177 (on Marco's recommendation) and at the time I think it cost €390 euro plus p+p - that was for the stainless steel version.
