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

Important – 2021 Euro 5 ONLY Triumph models 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.

Very easy to install and very much fun ;-)

It is exactly what the bike needs, it feels much better and a little bit more aggressiv. I highly recommend it in combination with a DNA Filter.

Bobber booster plug

I will admit to being sceptical about this plug n play booster plug however I was willing to try to remove the jerky throttle at low revs ....... it does what it says in the advert, noticeable difference after the 12min reset.
Throttle now alot smoother at low rev.
Some nice touch extras added aswell ... I would highly recommend this to anyone and the company

Speedmaster Booster plug

Easy to install has made a great difference would recommend it

Amazing improvement for my Street Twin 2018

The improvement of engine acceleration is significant. Also when riding in low revs, the engine works smoothly. I didn’t expected such a difference. How I could live without booster plug.

Excellent product

Well pleased with this product which was easily fitted to a Triumph bonneville t100 in less than 10 minutes.
Smoothed out low speed throttle control.
Also speedy delivery from TEC.
Well pleased.
