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

Booster plug

Fitted to 2014 T100. Had taken 1 baffle out of exhaust. Fitted booster plug in 10 minutes. Fantastic improvement. Removed low speed hesitation in town traffic conditions, stopped engine braking backfire and generally more responsive acceleration. Fantastic!

Scrambler snatch is tamed…..

My 2013 EFI Scrambler Had the typical snatchyness when going back onto throttle at low speeds round town. Read the boosterplug rebiews & thought I’ld give it a go. Kit looks well made, was easy to fit tho some zip ties were needed it to secure it so it didn’t drop down to wards the chain. & put strain on the connectors. Went for a test ride and what a transformation…no longer feels like i’m riding a bucking bronco when in slow traffic - well worth doing! Service & delivery from TEC parts was A1????????

Booster plug SE 2011

Parts arrived very prompt, good packing etc.
Clear instructions, fitted in 10 minutes.
The SE has been fitted with Norman Hyde pipes but with DB killers and the re-circulation taken off. General running was ok but it had the tendency to stall at a partial throttle.
After fitting the Booster plug the "bottom end" seems smoother and the weakness that appeared to be the cause of the stalling has been vastly improved.
I have only done in the region of 90 miles but on the first impressions the Booster plug has achieved the reason to fit it.

865 bonneville booster plug.

Plug, then went for a 150ml ride, snatchyness all but gone at lower speeds. Not perfect but a massive improvement. Not an easy fix on a big twin. Acceleration noticeably improved. This has made the bike more enjoyable to ride. Money well spent. Very good company to deal with.
Thank you tecbikes.

Triumph T100 Booster plug

Works as advertised smoothed out the jerking motion, and improves acceleration. Would definitely recommend.
