Ok ... first run with the modified tune which has the O2 sensors disabled and is slightly richer than the factory's lean settings.

Overall performance is very responsive to throttle - a bit more than stock. Very smooth at all throttle positions.

Snatchy throttle was occurring going from 0% throttle to 20% throttle using the Triumph aftermarket pipes map, making slow speed maneuvers difficult. This snatchiness is reduced by at least 50% with the modified map and is much more manageable. I very happy about that.

Popping. Still popping but maybe less loudly. Popping seems to be worse on a cool engine and the engine was already warm during my test run. We'll see tomorrow. I actually don't mind a bit of popping.

So far no downside.



Cheers, Richard
