If I was to upgrade, I would go with either the Align 500MX motor (I like the smooth "M" can better, but the MX with the ribbed can has better cooling) or the Scorpion HK-3226. But, I HIGHLY doubt you will see any performance increase. I would stick with the motor you have until you start doing some smack 3D. Then, you may want to upgrade to a higher wattage motor. The Scorpion that I posted is a 1770w motor and a max draw of 80a.
