Is it when your opening the throttle you will notice the difference?

By increasing the TPS to 26 does increase the fueling, but does not help with the cutting out when the throttle is closed. There is a small gain in power.
But it will make the bike surge more, as when the throttle is closed the air is shut off for an idle mixture, the extra fuel at this point will cause a run on effect & does cause a surge. I have done quite allot of playing with the TPS lately & found the best setting for my bike is 16, hardly any surge. There again I can adjust up my fuel mixture using my Fuel Mod to give me that extra power.
