[QUOTE="davidykhor, post: 430965, member: 18952"] This all is a bit over exaggerated imo ... Why not do and run before/after dyno test ? Its a bit like the ultimate butt dyno thing going on right now. Just like how sprint booster gives the feeling but no extra power, i believe in remapping they do adjust the throttle sensitivity level inside the drive by wire mapping as well, apart from the little gain u get from a n/a 6 cylinder. Same like how i put a sprint booster and say, hey go test your car out, then the wow factor came out, but on dyno sheet, fact remains that the feeling is not HP gains. For example a 525i goes from 215hp to a claimed 227hp, and 185nm torque to a claimed 196nm a 530i goes from 255 hp to a claimed 275hp, 220nm to a claimed 233nm. gains are low, and after the power runs down to the wheels, the loss is even more. Just my 2 cents, no other meanes. As we all know, the petrol 6 cylinder of bmw are petty much no more headroom for power as they extracted almost everything of it already. Anyway kudos to people who ramapped their car :) We're all enthusiast after all. [/QUOTE]
