MAKING MY BMW M140I FASTER THAN AN M2!

This video follows Mat Armstrong as he progressively tunes and upgrades a stolen recovered BMW M140i, transforming it visually into a look-alike M2 hatchback and pushing its performance beyond stock expectations. The host begins with a baseline assessment, noting the car’s current spec and the initial sound from a straight pipe exhaust that has already been fitted. He then conducts an initial 0-60 test using a Draggy app to establish a performance baseline, recording a time around 4.6 seconds before aiming to improve with a tune. The team then visits Mallory Performance to explore tuning options, and a first dyno run reveals a strong but potentially tune-dependent baseline output, with a dramatic exhaust note that turns heads in the workshop. Through the video, power figures are incrementally increased with a Stage 1 tune, and the team documents the progression from stock to lightly tuned to more aggressive tuning, while also highlighting the importance of fuel quality and proper setup for maximizing gains. By the midway point, the car is shown to be significantly louder and more powerful on the dyno, with a measured output approaching 435 horsepower, suggesting the presence of a tune and possibly additional modifications still being tested. The final segments reveal a plan to push the M140i even further with a Stage 3 tune, driven by a hybrid turbo and a high-pressure fuel pump, which could propel the car well over 550 horsepower. The host hints at a future comparison against actual M2s and teases additional installation steps, including a turbo upgrade and more powertrain work, to seal the car’s place as a high-performance project. The video closes with a call to subscribe and a teaser for the next installment, promising more speed, more torque, and more dramatic head-to-head track or drag results against real M2 rivals.
