Try this kid.......
Just open the gloss dds and you'll see what I did, meh I'll just explain. Take the texture from the diffuse and de-saturate it, go to Color/level and tweak the brightness to what you want. I just basically made the texture for the emblem whiter in the diffuse than went to the gloss and de-saturated it and leveled the brightness. I made a normal map for your texture, to get the lighting right, I think it's right!? lol ......anyway this took me 10 minutes, super easy. Should consider cleaning up your textures in the diffuse, make'em nice n' clean. Your emblem texture is a lil' "choppy" ,it's all good though,I cleaned em' up just a bit
