Booster plug

[lieberty64]

I ride an 03 1150 GSA, all is great except from time to time, going down the gears it suddenly cuts out on the little rev burst.
My previous 1150 & 1100 gs's used to do the same.
I noticed a product called "booster plug" which sounds as if it would do the trick, anyone have any advice or experience with it?

I've had a booster plug, personally I'd go down the route of the more expensive but more effective lamba shift. Read the johns chip thread. I've effectively done the same thing using a pc3 because I picked one up cheaper.
