N55 jb4 going into map 4, clutch smell?

Hey guys so I just uploaded the new hex file for my jb4, after doing that, I put into map 5, did a quick wot and it was fast, but after checking my car map, it was on 4 and I stopped and my clutch was smelling crazy (didn't launch or mis shift) I put it back to map 5, did it again, back to map 4 and my clutch was smelling again. Anyone have this experience?? Let me know, thank you.

did you ever figure out anything with this? i just got my car FBO last weekend and i keep my car in map 5 and it stays on map 5 but when i go WOT it pulls like a bat outta hell then when i slow down i can smell that clutch burning smell. my car only has 16000 miles on it. does anyone know what the max Torque rating on the stock clutch is? maybe we have surpassed that and its starting to slip a little? i really have no idea cause it pulls great. and this isnt even from a stop these are mostly from rolls that i am getting the smell.
