I agree it should be a typo...the tuning for the M3 is also $640 and that should be much more complex...but it doesnt appear to be. If you look at the detailed data sheet it breaks down the price and hp gain and gives a price/hp of around $80. On that sheet it repeats the same price of $1490 which seems very high.
Also, this same price is listed on other valvetronic engines, so that may be the problem. The chip for the 645/745 is also $1490, but it take power from 325 hp to 351 and torque from 330 to 353. I'm not sure why there's a bigger jump for those cars vs. the X5.
