Anybody got any tips for boxing?

ok i do mma, i have for a few years. i onjured my knee a while back and i stoppen mma cause of the kicks and joint stress and did boxing for a while. i had great speed and footwork but my knee heeled and i been back in mma for about 6 months. anyways im going to box in a match in about 2 months and i just found out yesterday lol. so anybody got any tips, anything you would suggest to do or not to do.....but just to let you guys know im not much of a power hitter, im more of a speed boxer.
