For your Tundra, and I am speaking from experience, don't get a full cold air intake. All they do is make more noise. If you want to change anything switch to the drop in air filter from either AFE or AEM. I don't remember which. You will get a better filter that is dry, it flows better and it is quieter. A hyper tech will get your 7-8 rwhp. the only thing that really works is a supercharger for power or long tube headers and a full exhaust. The bullydog is a waste of money until they release some programing that actually works. Hopefully some day...
