| I dont have a SXX Stock or TC Spec, but I have a Tekin RSPro which I can turn on or off turbo. 
 All I can say is Stock mode + Stock motor is MUCH faster than Mod mode + Stock motor, assuming the same motor.
 
 As mentioned, in Stock mode + Stock motor, both motor and esc are hotter.  Thus you will have to gear down (ie increase FDR) and keep an eye on the temp all the time.
 
 eg: I tried Stock mode + 11.5R motor, the speed can match a 5.5R on the straight, but the motor temp after 5 mins is about 80C.
