X3 M40i stage 1 - family SUV turned rocket

2 months ago· 19 posts

Tuned my G01 X3 M40i B58 last week. 385hp stock, now 430hp with stage 1. The wife doesnt know yet lol. Seriously though, this thing is stupid fast for a family SUV. 0-100 in about 4.2 seconds. The B58 responds so well to tuning. Anyone else running a tuned X3?

B58 in the X3 is the same engine as the M340i. Responds just as well to tuning. Great choice.
