So i recently installed a chip tune from racechip. Love the power increase and its definitely noticeable. Only issue is that i get sort of a clinging/tick when i full throttle when the tune is on. Ive noticed that it typically happens in warmer temperatures, have never noticed it under 65° F (if i remember correctly). There is a power difference considering temperature as well which is of course obvious but i was hoping anyone could have answers or have experienced something similar. Just today i had the racechip (via bluetooth control app) in racemode to push on a 335i sedan and it was just clink tick clink then the second i disabled the chip it was smooth as a bug in full throttle. I have yet to see a CEL, and everything seems ok externally.
