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.

Triumph Speedmaster 2019

The throttle on this bike was a switch, it proved impossible to bring in the power from a closed throttle without using the clutch. This is ok when changing gears but annoying if creeping along in traffic or if you’ve closed the throttle and wish to open it again... very ‘jerky’ ride. With this unit fitted, I still have to bring in the throttle ( from closed) carefully but I can now do it smoothly and without the bike trying to throw me off the back. Worth every penny.

Booster plug t120

Having fitted the booster plug I done a tour of the north east taking in a route from Penrith to Rothbury with many tight uphill hairpins the engine behaved totally different at low revs pulling out of the bends it was smooth no jerky moments it is also smooth in roundabouts second and third gear low revs and picks up cleanly a piece of kit well worth fitting. Overall does everything Tec say about it.

Quick and easy upgrade. 10 min mounting!
The Tec Booster Plug really did as promised . Way smoother ride in first and second gear. No stalling and the throttle response is instant. My T120 is much nicer to drive with the Booster Plug and DNA High Performance filter installed. Great service and fast delivery from Tec Bike parts

Better than before

These are so fast and easy to fit and has helped improve low speed smoothness. I also fitted Triumph throttle spacers which removes all the play in the throttle movement. I'd highly recommend them (Check out Ducatispacers.com). Also got an Xpipe from Tec but not fitted yet which I believe makes quite a difference too.
