The wastegate on the Can-Am X3 is an integral part of the turbo system and ECU tuning. A wastegate is designed to stay closed allowing the turbocharger to make boost pressure under throttle. What keeps the turbo from making an infinite amount of boost pressure is the wastegate spring. The spring in the wastegate determines when the wastegate will open before the factory boost solenoid takes over. In the ECU program, boost is set to a value that may exceed the wastegate spring. For example, the stock boost pressure of a Can-Am X3 is just under 1 Bar (14.7psi). The wastegate has a crack pressure of around 6psi. So the ECU is controlling the boost solenoid to keep the wastegate shut until it reaches its set pressure that allows it to open.
When running higher boost pressures than stock, it is very common to upgrade the wastegate on a turbocharger to improve the boost response and prevent any potential wastegate leaking. On the Can-Am X3, it has become common practice for some to simply adjust the wastegate preload to change the crack pressure up a couple PSI. For roughly every 1 turn, you get .5psi increase in crack pressure. If you wanted to set your wastegate to crack at 1bar, this is about 16 turns. You can reach a point where you are limiting the wastegate rod travel where the spring is barely functioning. This is why an upgraded wastegate will have a stiffer spring allowing you to keep the wastegate closed with less stress and potential for failure.
The new Agency Power billet aluminum wastegate is the perfect upgrade for your Can-Am X3 turbocharger. The new wastegate features a 1bar spring housed in an 85mm body. This design allows you to easily change springs and service the wastegate if needed. As a direct bolt-on to your factory turbo, the wastegate features an adjustable rod for those that would like to set your crack pressure specifically to your build. Perfect for those looking to get better boost response out of the stock tune, an ECU flashed car or even a turbo upgrade.
Doing a back to back dyno test, we show how the wastegate improves boost response and performance over the stock wastegate. Set at 1 full turn in from neutral, the new Agency Power billet wastegate holds 1 psi more than stock gaining you 4hp.

Hi Brian,
I’ve got the 2018 Maverick X3 with your Flash. I really notice the quicker throttle response and midrange power but haven’t noticed much top end speed or rpm change, would your wastegate update improve any of this?
Also is this something I can install , set or tune without any special tools required or is it preset?
Thanks
Shawn T
Hey Shawn,
We still got something for you we are working on 🙂 When we test the cars, all the power gain is really in the mid to top end. This is really apparent on this 2018 we tested that also had our valvetronic dump pipe here – https://www.vividracing.com/blog/vividracing-client-cars/2018-can-am-x3-ecu-flash-dyno-test/. Now you can see similar results here https://www.vividracing.com/blog/vividracing-client-cars/2018-can-am-x3-turbo-ecu-tuning-with-video/. I really feel the valvetronic dump pipe is a world of difference on these cars. We have an article being written right now with dyno comparisons to an exhaust with cat delete and stock cat to share next week. We even did a back to back comparison with those “other guys” Stage 3 flash with identical results to our ECU Flash. Clutching makes a huge difference in these cars for the top RPM as well. The wastegate is a good upgrade to help keep boost pressure consistent. You do need to set it up though as seen here https://www.agency-power.com/how-to-install-agency-power-wastegate-can-am-maverick-x3/
I should have something back to your support ticket to test by tomorrow.
Thx!
Dan
