What tires are you running? If you have typical 1/8 tires, they are 4.5" and with a little ballooning, you are geared for around 60mph with the 1509... way high unless you are trying to just do some speed passes. Get the 3.3 diffs in it, and drop the pinion a couple teeth. That puts you more like 40mph on the calc which is still fast for a MM/1509 but it's a lot better than 50-60mph
