We are very pleased to be able to now offer a full Stage 1 engine remapping for the MG 3. Giving “substantial” performance increase across the gearing range combined with an increased MPG.

This not and add-on part procedure but true ECU internal software remap, being totally invisible. The test car was a 2016 model with our 2” Stainless exhaust system and High Volume Air Filter fitted. Exhaust and Filter not essential to achieve excellent results they were already on our test car.

Test results on the Rolling Road were initially 109.8bhp to 126.3bhp combined with appropriate engine torque increase. As the photo from the Rolling Road display screen indicates.

There are two options:

1/ Send your ECU to us for the full remap service, just refit to your vehicle @ £185.00 (Includes return P & P).

2/ Bring your 3 to us and have the work carried out while you wait @ £200.00
