Firstly, I apologize for bumping a mildly old thread, but since I was having the same issue, and this was the one of the first threads I ran across after a Google search I figured I might throw in some advice. I just ran the auto-tune function on my E3D hot end. After a little bit of piddling, I found that I could get it to run without over shooting the temperature range by pre-heating the hot end to 200. The G-Code needed should be M104 S200 in Marlin. From what I've read, others might have issues trying to run the auto-tune on a heated bed without pre-heating the bed. Anywho, my results were: Classic PID Kp: 9.12 Ki: 0.41 Kd: 50.98 PID Autotune finished! Put the last Kp, Ki and Kd constants from above into Configuration.h Hope I helped!
