Hello everyone, this is my first post here and it might be against the rules, if it is i am sorry for that.

I bought used 2001 BMW 525D E39 and the owner told me that the only issue the car has is the delay in the turbo (the car is a monster after 2300rpm but before that the turbo doesnt really kick in, he said the turbo problem began when he got a tunning for stage 1) I got a kess clone and downloaded the file but I have no experience how to tune it. Can someone maybe just check whats wrong with the map and point me in some directions or fix it right ahead. Thanks!
