I would usually not even think about it. But since I have an 03 325i laying around useless, I thought maybe I could have some fun with it. And just a few minutes ago I saw it on TV that they took a 364 hp ford to 407 hp within less than one minute by reprogramming it with a device from hypertech. That is an increase of 43 hp within seconds.
Is there such a thing for my car too? if yes, how much does it increase the hp? and is it safe?
