How it works
Thorton Performance Chips are engineered to unlock the true potential of your BMW. Our plug-and-play design delivers more horsepower, more torque, and improved efficiency — safely and effectively.
The OBD2 port is typically located under the dashboard on the driver's side.

Start your engine. The chip will automatically communicate with your vehicle's ECU.
Experience more horsepower, more torque, improved throttle response, and better overall performance.
Unplug the chip at any time to return your vehicle to its original factory settings.

BMW Performance Chip
OMG!!! Absolutely amazing … installed on my 1999 M Z3 Roadster (3rd owner, 40k pampered miles) and was shocked at the instant improvement.
Car is now a Sports car !!! Throttle response was immediately noticeably improved! After a few gentle miles I got on the throttle and it’s a different car!! The car now LAUNCHES HARD with a noticeable squat !! Took off ASC and was amazed at the launch and tires smoke!! Now I’ve got to strengthen the subframe as it’s a ROCKET!!!
I purchased 1for my Cadillac unbelievable it woke my suv rite up liked it so much bought 1for my other vehicle what a performance gain👍
I bought another CHIP Stage 3 for my wife MUX 2023 Diesel 3L. We have a caravan. Her car was consuming up to 11.8 L on towing trips about 150km before, without this chip. After I put it in :Chip kicked in after day or two her driving, CONSUMPTION went down to 10,3L-10,5L on same trip with caravan.
Also, she says, that now her new MUX with CHIP does not jump auto gears unnecessary, car drives smoother and quicker during normal driving.
MUX is a great car, and CHIP makes it purrfect…:)
I have a 2025 BMW M240 XI about 10 months old with 7500 miles on it. With only a K&N air filter It is pretty bad ass.. I put the Thornton 40 hp chip in and within 15 miles the power and the harder shifting is totally unbelievable. It is just amazing from a little bit of chip.. I highly recommend it😜
I’m very happy with stage 2 chip on e83 X3 diesel 3L. I drove whole month: midrange increase response and power/ torque.
Mileage from before 7.8l gone to 8.3l , if push hard 8.6l.
Yesterday I remove chip I car drive like in chains:) I put back today, much better. Oil is not getting dirty ,as I expected before. Good news. But I will change in 5k, just in case.
