Description
TSP ERM Power Kit TBI – 2024+ KTM/Husky XC-W/TE 150cc Models
This TSP TBI Power Kit fits 2024+ KTM XC-W and Husqvarna TE 150 models with the new 150 TBI (Throttle body injection) engine.
This is not designed for 150 SX/XC Models
This package includes:
- A TSP ERM with TSP ERM Rain & Dust Cover – which allows you to flash the necessary tune to your ECU. The ERM also allows simple adjustments to fuel, ignition and power valve in case you want to make changes, plus its a valuable service tool allowing you to set the TPS and read/clear fault codes – See more information on the TSP ERM website.
- A new 2 piece TSP billet cylinder head. We currently offer a single compression ratio which is higher than stock but still very safe for 91 octane pump fuel
- Head O-ring & Washer Kit
- NGK spark plug suited for the TSP tune and head
This package makes a huge difference to the 150 XC-W over stock, with some key features being:
- More power throughout the rev range, at all throttle positions.
- Approx 2-3hp gain in most areas
- Both Green & White maps are tuned and the stock map switch works like normal to select between the customized maps. The Green map is Hard/Aggressive, the White map is Safer/Softer.
- Much better bottom end pull, makes hill climbs and lifting the front wheel easier
- Increased oiling over stock
- safer air/fuel ratios at high rpm and large throttle openings so the engine is safer during prolonged high speed running
All TSP mods are designed and dyno tested in-house at TSP so you can be sure you’re getting reliable performance for local conditions.

I am shocked at the performance improvement of this package. Throttle response improvement makes this bike so much more fun to ride.

I installed the ERM Tune first and rode my TE150 for 2.5 hours on trails that I am very familiar with, and the improvement was very noticeable. Cleaner running engine sound and smoother forward traction in technical sections. Then I installed the compression head with the included new spark plug. I was immediately surprised of the noticeable increase in power with even more smoothness while chugging along in the woods at very low to medium RPMs. My two riding buddies on KTM 300 XC’s thought I was on a TE300 and said my Husky sounded bigger than a TE150. If I do buy a TE300, I will install the TSP kit immediately after the 5-hour engine break-in period.
