New Slash With MM/VXL on 3s!!!

Hey guys just took my new Slash on it's first run....WOW! it flys . It has a Velineon motor and Mamba maxx esc in it
running on a 3s TrueRc batt. Geared 18/90. It was about 65f outside, battery = 96f, esc = 117f and motor = 155f. I have one question, is 155f pushing it on a velineon motor? I will try a 23 tooth pinion and see if I was undergeared. Pic/Videos within the next 2 weeks.
