Modern EFI bikes especially Euro 4 run very lean in open loop mode and this can cause stalling, poor running and hesitant acceleration.

This fuelling device interrupts the signal from the air temp sensor and modifies it to make the ECU add approx 4-6% more fuel during acceleration in open loop mode, it will not affect MPG as it has no effect in closed loop mode ie. cruising mode or steady running. The device has its own temp sensor and it modifies the signal to release the correct amount of fuel for the measured air temperature.

Very easy to install with correct plugs and no wire cutting required. It has a no quibble money back satisfaction 60 return and a lifetime product limited warranty

Boosterplug for Triumph Thruxton 900

Fitted this boosterplug very easy . And what a difference its made . Much smoother low down and also on pick up. Very pleased with it . Thankyou.

The Booster does work and noticably.

Tried a booster on another bike and did make a marked difference. So tried it as available for the Air Cooled Bonny and it has also noticeably improved tick over, low throttle smoother response and a more linear and smoother acceleration on the throttle and less popping on overun, Like most machines they are programmed to run I feel too lean but the booster has given imho a real improvement for a reasonable and uncomplicated cost.

It’s good!

It does work. The booster plug takes up that slack area at the very bottom of the Rev range. So there’s less snatch on and off throttle. There’s less pop from the exhaust too. I defo recommend it.

Very good service and product

Very good and quick service. Works very fine.
