OP OP! An article about my wife’s car — this is a BMW X5 E70 with an M57 engine and twin turbos.
Before chip tuning, the car was put on a dyno, and the power was 300 hp without any tuning.
Then we went to BMW Service Beresteiska, read the tune, and saw that the injector opening time had already been increased. We uploaded Stage 1 and went to test the car on the dyno.
After uploading the Stage 1 tune to the engine, we achieved 312 horsepower on the dyno.
0-100 acceleration measurements:
STOCK 0-100 km/h – 7.2 seconds
STAGE 1 0-100 km/h – 6.3 seconds
After Stage 1, we decided to upload the Stage 2 tune, and on the dyno, we got a stable 370 horsepower. The 0-100 km/h result was 5.5 seconds.
We also uploaded the Stage 3 gearbox chip after Stage 2, and the 0-100 km/h acceleration time remained the same — 5.5 seconds.
During the measurements, the boost pipe broke, but it was replaced, and the car continues to drive perfectly.
