I'm a noob to bmw's but I've been in the tuning scene for about 10 years. 40whp from a tune on a stock car is rediclious!

i felt the same way too. tuning american cars(vetsc5) and z28 net good results but took a lot of trial and error and a host of questions on those forums. that being said to literally plug and play with no learning timing,fuel , load and a lot more parimeter to make it all work properly i truly know for a fact it is the best mod ever!
