Important – From 2021 bikes began to be made to Euro 5 regulations.  If your bike is Euro 5 (if unsure speak to your dealer before buying) you CAN NOT fit any form of tuner, including BoosterPlug & Power Commander.  This is due to the ECU having anti-tamper software.  Doing so will cause the MIL light to come on.

Do you find your EFI bike prone to stalling at low engine speeds, lack of throttle response and a lumpy feel to your motor?

Have you fitted a free flow exhaust and worried about it running too lean?

Then this plug and play device will resolve these problems without the need to re-map you ECU.

Fits all 900cc -Street twin/Street Cup/Street Scrambler/T100

and 1200cc- Speedmaster/Bobber/T120/Thruxton/Thruxton R/ Speed Twin

Is not compatible with Thruxton 1200 RS

Just email us your model/yr when ordering

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 ( PLUG AND PLAY ) no wire cutting required. It has a no quibble money back satisfaction 60 return and a lifetime product limited warranty

booster plug

After riding my 2017 street scrambler for a while I noticed that at very low speed the throttle response was very jerky , it was either accelerating or slowing with no sweet spot in between. After fitting the booster plug unit the problem disappeared .making for a much more pleasant ride.The booster itself was easy to fit . Happy customer !.

It Really Works !

I was interested to see if this Booster Plug actually made any difference to my 2020 S Scrambler 900, and I am delighted to report it does ! Gone is the 'off idle fluffiness' and now the engine pulls strongly and with a much more linear response in the lower rev range, delighted with result. I have fitted Free Spirits DeCat exhaust, and the little plastic widgets which take up any throttle cable slack, the machine is now much nicer ( it already was a lovely bike to ride ) to use, just fantastic.

Is it worth it?

I fitted Slash Cut pipes to my 2017 Street Twin a couple of years ago (which was nice). When I put the bike through its MOT recently the tech showed me what was happening to power at low revs, and recommended that I fitted a Fuel Booster. Delivery from TEC was quick and it's just 'plug & play' to fit. And yes, it is worth it - The bike is much smoother in slow traffic and filtering.

Booster Plug (T120)

Fitted this to my 2019 T120 (Euro 4). Instructions supplied are a little vague but there are plenty of videos on YouTube so you can’t go wrong and is very easy to fit. Once fitted, I let the bike idle for around 10 mins or so until it completed a heat cycle ( i.e until the cooling fan cut in and then stopped) This apparently ensures that the ECU has ‘learned’ the new parameters. Has definitely helped reduce the snatchy throttle at low speeds making it easier to negotiate mini roundabouts and town traffic in general. I believe removing the Cat and replacing with an X-pipe would improve things further. (Not done this on mine) TEC service was efficient and order arrived on time.

Works 100%

Totally eliminates the problems of a cold start. My Bike used to struggle the first couple of seconds after I started it, as if it was very cold and not getting enough fuel. Does not influence the normal running of the bike.

Fuel booster plug 2020 t100

Ordered and arrived a few days later. Installed and all good. Only been able to go for a short 50 mile run so far. Seems to have improved the jerkines but need more miles to be sure. I have ordered a number of items from tec and all have arrived within a couple of days of purchase

Triumph booster plug

Fitted the booster plug to my street twin, after reading the reviews, the slow speed running is less 'fluffy' and riding in traffic is much smoother, fuel economy is pretty much the same. I wouldn't describe it as transformational but I would definitely recommend, generally makes it a smoother ride.

Speed Twin 1200 hesitance and jerking

After a recent additional motorbike purchase, I was a little disappointed with the low revs and light throttle behaviour. Especially after my excellent 2011 Street Triple 675! So after research I have fitted the 'Ducati' throttle spacers which did help with the jerkiness and now the booster plug to address the horrible hesitance between 1500 and 2250 rpm as I do like to potter around on occasion! When the bike is cold and therefore running a richer mixture it is fine so I guessed the booster plug could be good! Yes, it is much better, especially when combined with E5 99ron. A result!

Excellent!

Was a bit worried this might be snake oil, but it really worked! Huge improvement on idle and throttle response from idle.

It works.

Was a little bit sceptical having seen varying reports, but have found that it has made a significant improvement to the low speed response and overrun burble. A much nicer bike to ride now..

Street Scrambler now refined

Excellent service as is normal from TEC. Booster plug has made a significant improvement to the low speed running and acceleration. What is particularly noticeable is the viby running that used to come in at about 3500 rpm has all but disappeared. Don’t know why I waited 4 years to fit this and the free flow air filter! Different bike now.

Not had a ride out yet!

Easy to fit & started up first time. However being a fare weather rider. I have yet to feel the benefits. I have submitted 5 stars as a few colleagues have installed the fuel booster & swear by it.

Booster plug, bar end mirrors, big bore dueller exhaust, DNA filter.

I have to say the customer service is outstanding and the quality of the parts speaks for itself. Had a minor issue with an exhaust gasket (no fault of TECs) which they replaced promptly free of charge. We’re on hand to help with queries/ offer advice on kit which is exceptional value for money and looks/performs fantastically. A genuine and quality company - breath of fresh air.

VERY EFFECTIVE MODIFICATION

The Fuel Booster Plugged, which I fitted in conjunction with the DNA High Performance Filter, has certainly improved acceleration from a standing start. The idle is also smoother and the flat spot at lower rpm is also gone. Deceleration under engine braking also feels much smoother. I was also impressed with the very fast shipping. It arrived early and much quicker than I expected given it had to travel halfway around the world. I did need to go to the Fuel Booster Plug website to get more information on fitting the plug. I was specifically looking for more guidance on where to place the temperature sensing probe and to get a clearer image of where the find the AIT plug as the black and white printed/photocopied page provided was not clear enough for me to be sure I had located the right plug. Overall I am very happy and the systems works as advertised.

Definitely made a difference, you can pull away on tick over without stalling, instructions very clear, one issue it says secure the temp sensor ideally somewhere behind the headlamp but it won't reach so its by the air intake left hand side cover.

Worth it

After dealing with a snatchy throttle and a bike prone to stalling at the lights I decided to give this a go. Definitely worth it especially if you're messing with the engine's air flow (filter, X-pipe etc.) and Tec customer services were their usual prompt and friendly selves when asked for advice. Highly recommended.

I fitted it to my Street Scrambler 900 and the biggest difference was when maneuvering on the clutch with no throttle. It's far less easy to stall now. Makes it easier to creep forward in a queue etc, and for that reason alone I think it's worth it. I would say it is also less jerky when you come on and off the throttle, nothing major but it is noticeable. However, I can't say I have noticed it remove a flat spot when accelerating or anything like that. It's very easy to fit.

Booster plug

I was pretty sceptical about the booster plug especially at the price but have to say it has made my 1200 Speed Twin run smoother and has helped with the main problem I had with riding in city traffic. Not a cure but an improvement. Delivery was pretty quick as well.
