I would keep your calorie intake the same to start because while cardio burns more calories while you are performing it, muscle burns more calories all the time. You should be putting on muscle and burning more calories if you are lifting heavy.
Take some measurements now and remeasure every month because you might even put on a little muscle weight and that's okay. It's more important how your clothes fit and those measurements.
If you start gaining fat, which at that calorie intake and workout regime would be hard to do unless your diet isn't great, then you could cut back on calories. It would make much more sense however to look over you diet and clean it up to acheieve the results you are looking for.
