Description
TSP TPI Power Kit with ECU Reflash 150 TPI
This TSP TPI Power Kit with ECU Reflash package will transform the power delivery of your TPI. The TSP Power Kit includes the following:
- A new TSP CNC machined cylinder head insert. This design is higher comp than stock but still suits normal 91 octane fuel.
- The TSP head includes a complete head gasket kit
- Reflashing of your STOCK ECU with improved fuel, oil and ignition maps developed by TSP. We modify both Map 1 and Map 2, with a more noticeable difference between the maps compared to the stock maps. Both maps have more oil everywhere compared to stock. Map 1 is the fully tuned map delivering maximum performance. Map 2 has less ignition advance and more fuel than Map 1 and is softer everywhere. Map 2 is the ‘safe’ map we suggest using for prolonged high speed riding, deep sand, or if you want to temporarily reduce power in very technical terrain.
- A new NGK spark plug, better suited to the improved power the engine makes with this kit
- 50 mm bolt and spring necessary to do the ‘idle screw mod’. Not always necessary to install but we supply it just in case.
Our 150TPI kit increases power throughout the rev range, making approximately 2 hp more up top and 5+hp more through the mid-range making it a weapon off-road.
In order to change the stock ECU data we have spent hundreds of hours developing our own process for accessing, changing and reloading the ECU data. This is not a service you will find anywhere else for the TPI models!
The stock ECU will still connect to the KTM/Husky diagnostic tool and the dealer can still perform all normal service tasks. In fact, they wont be aware that the ignition and fuel data has been modified. All other ECU features work normally, including oil injection, fan and warning lights. There are no issues with hard starting and no need to tune via apps or software. Just install and ride!
We provide an idle setting bolt that can be installed if you feel the need to change the idle speed or air screw setting after fitting the kit, however the vast majority of bikes will run fine without it.
This kit has been developed to work with the stock exhaust and almost makes aftermarket exhaust systems obsolete for the TPI. The head and ECU give a WAY bigger gain in performance than any aftermarket exhaust can offer, and there’s no trade off by taking power from one area to improve power in another, as usually happens with pipes.
We supply complete installation instructions plus recommended settings for the air screw and power-valve pre-load adjuster.
This is the ONLY complete solution currently for sale on the market that addresses all the necessary TPI issues – head, ignition and fuel. It is also the MOST COST EFFECTIVE solution by far. All other solutions are either more expensive or only tackle part of the problem. In order to address all the necessary issues using other parts you would need a programmable ECU, an aftermarket head, a new plug and an idle screw. Buying all these separately adds up to roughly twice the cost of our package!

One of our favorite upgrades for the 150, brings the power out for trail and desert riding

Great communication before and during purchase! Very helpful with questions, the kit/parts seem quality, and most importantly this resolved the gurgling/poor performance my 150xc had with the original tune.

2023 TE150 were running like garbage, fouling plugs and not hitting right. Anyone reading this, pay the money and get the TPS Power Kit! It has been game changer on every level. The most linear pull, great for woods and no loner fouling plugs. Thanks South Bay

Super fast to re-flash my ECU and ship. Nice increase in mid power band. Mid to hit seam is smoother improving the rideability. I feel better knowing the oil injection volume has been also improved, and the added map switch is handy.

2020 ktm 150 xcw- tpi with new piston kit and map switch . WOW!! My bike was un-rideable stock . Spitting,coughing,bogging . This kit fixes that and it runs so crisp now !! I’ve had this kit installed for awhile but waiting to do a review till I could get a good ride on it . Just did a 2hr race this past weekend and everything held up great ! 6hrs total now since install. Dont hesitate to purchase this kit, it’s an absolute must !! Not to mention South Bay customer service is 100% . Very pleased with this purchase and would have sold my 150 had I not found this!

So far this TSP power kit has been an excellent upgrade for my 150 exc TPI. A real noticeable improvement in mid range power and lugs better on those steep technical trails. No more sputtering or hanging idle and did not have to install the included idle adjustment screw. Having the ECU flashed for my typical ride elevation also may be contributing to the better performance. SB Moto turned it around in a day and were great to deal with. Thanks

Super pleased with the performance gains, great communication and very fast turn around, you will not be disappointed.

Great fit and finish the machining is perfect. The tune is awesome. Everything works great together.

I’m really impressed with the overall improvement. Much smoother down low and once dialed in with the air bypass and exhaust power valve, it’s pretty smooth all the way to the top. Overall, I’d say there is a power gain, but the real improvement is how much more civilized it is. Easy install, good instructions. Excellent customer service. Answered every question I had.

My 2023 Husky 150TPI bogged under the pipe unless I abused the clutch. When it did hit the power band, it was like all or nothing. I really didn’t enjoy riding it. Steve really helped me understand how the ECU re-map and head would help. It was super easy to install (and I’m more of a YouTube mechanic). The bike runs super smooth now. much more linear through the power band and doesn’t bog. It has a lot more torque in the low end as well. I wish I would have done this last year!
