I'm planning to increase the horsepower of my BMW 1.16i along with some additional make-up modifications.
If I'll be making the horsepower upgrade, it will happen using the official software from Evotech via the official distributor of Evotech in my country.
Also my 2 year guarantee is almost up so burning up the guarantee is no hassle.
My question is that is this a wise decision? I heard that 1.18i has nearly the same engine as 1.16i does and basically BMW produces 1.18i by merely changing it's software. Is this correct? Will me making this hp modification risky that it will make my engine unstable or produce some problems in the future.
Also is it possible that if I make the hp increase, will my 1.16i burn less gas since I'll have more hp to move the car? Or am I completely wrong?
Does anyone have any thoughts or better yet any experiences?
