I have. Got the Tec Cam installed in my 2017 T-120 Bonneville. I have x pipe , TBR slip ons , snorkel removed , K & N filter and power commander. Waiting for the weather to warm up to dyno it. The dyno guy wants 15 deg c weather. I live in Edmonton Alberta Canada.

Here is a dyno BEFORE the Tec Cam. This was with the slip on pipes , x pipe , snorkel removed . K&N filter and power commander. Almost 77 hp at rear wheel NOT corrected to sea level

I will post TEC Cam Dyno as soon as I get it done. I have not heard it run but the mechanic said it sounds great.

I have a 2018 t120 and have read reviews online about the Tec bike parts cam for the T120. They all say it is just very good and gives a lot more power and more to the point for big twins a lot more torque.
If you take a look at a standard T120 cam you can see the outlet lobe has no where near enough lift on it. This supresses the power and was done to comply with EU emissions control as was the CAT.
The standard cam has good lift on the intake side and so to make real power there has to be enough lift on the outlet side to evacuate all the gas and there isnt. This is why the TECBIKE PARTS Cam works so well.
I will be buying and installing one as soon as they come back from Quarantine.
In the meantime take off the left side cover and remove the air snorkel buy undoing the one torque head screw and pull it out. I did and I can tell you it gives a very noticeable increase in power and torque and she roars from around about 3500/4000 up. I can now accelerate in 6th gear from 80 to 180 kmh (115mph +/-) very quickly, quicker than it use to be. You will see how long that snorkel is. It goes all the way into the air box and seriously restricts the airflow. More air in = more power out. With the snorkel off, good pipes on and the TEC cam fitted these engines will fly imo. You wont get the benefit of good pipes until you fix the outlet valve lift with the cam no matter how much your pipes cost. Engines rely on air in and gas out being fairly equal in volume for performance and at the moment the T120 series isnt balanced.
