Is this right?

I was flying a BF109 G-6, in a sim dogfight, against a single other person in a Spit II. Somehow, he managed to out fly me and out turn me in every single battle. I set my elevators to high sensitivity, I'd put combat flaps on, I'd try everything, but he just wound up behind me every single time. I'm given to understand that these two planes are somewhat equal, so how could he out turn me everytime? I'm not being petty, I could have him in my sights, and we would turn a circle and he would end up on my six in a matter of seconds! How is that possible?
