Which contest? Leheigh Valley?
Anyway, I would cut the carbs down to 100-120, up the protein, and drop the fat down to 25 or less. That's just me though. I've found massive success with extremely high protein diet for contest prep. Was 217 at Thanksgiving, and currently I'm 170. Almost 50 pounds in 4 months ain't too shabby. Even packed a little extra muscle in the process.
With such little time you have no room for error. You're going to have to diet hard to dial it in. I suggest immediately start taking Melting Point along with some Sesamin. Drop the MP 3 weeks out. You will gain a little weight from MP in the beginning; but it's all waterweight.
Do that, along with a very high protein skewed diet (I would say 65/20/15) and a caloric deficit. It will be tough but if you stick to your guns it's possible.
