exactly ive done that same friends m3 (bms stage 1,res delete, intake) and was identical to the m5 stock (no surprise there). but this is really weird. i did a 4th gear pull with brother in m4(bms stag 1) otw home and the m4 pulled. i contacted bms to see if the unit could be faulty but i think the culprit is the heat. i think s63tu has some serious issues with heatsoak. we have like 20-35 degree weather here so i think that plays a roll. how i came to this theory (yet to be proven) is on a fun run brother stomped on gas and i reeled him in from pre dam far back starting way later than he did. wanted to see if anyone on forum was experiencing this inconsistency with f10 m5 tuned.
