Boosting Your BMW X3 M Just Got A Lot Easier

/ Comments

The power upgrades are shockingly simple.

The BMW X3 M is a hilariously excellent SUV to drive enthusiastically, particularly if you like a lot of oversteer and enjoy wagging the tail while leaving tire smoke behind. However, there will always be people that demand more power. That's where Pro Tuning Freaks has stepped up and delivered.

A user over at Xbimmers.com has used Pro Tuning Freaks' flash tuning platform to upgrade their 2020 X3 M with the company's bootmod3 software using its OTS Stage 1 beta map. They then put the SUV on a dyno and, as you can see from the published results, there's a considerable amount of potential.

The baseline was set with a stock pull on the dyno showing the X3 M generating 459 horsepower to the wheels along with 429 ft-lb of torque. Running the Stage 1 beta map on 93 octane gas, those numbers jumped to 551 hpr at the wheels and 532 ft-lb of torque. That's a bump of 92 horsepower and 103 ft-lb of torque on just an ECU reflash alone.

On E30 gasoline (30 percent ethanol), the number improved even more with 579 hp shown at the wheels and 572 lb-ft of torque. That's an extraordinary increase of 120 hp and 143 lb-ft of torque over the stock figures recorded.

Not happy with just dyno readings, they then used a Dragy GPS Performance Box to measure a 0-60 mph time from the modified 2020 BMW X3 M of 2.96 seconds.

That's a massive gain in power and a blisteringly quick acceleration time, to say the least, and shows just how much BMW is leaving on the table from its S58 engine for tuners to exploit. It's the same engine that is going into the new M3 as well, so we'll definitely be seeing just how far the M division's engine can be taken.
