There's Super Chips Cortex Programmer, Hypertech Programmer and of course the Bullydog Triple Dog GT Gas Tuner. Do you think these performance chips are worth it? What are your performance gains?

i have installed the bully dog gt on my 09 pro4x4 and i love the custom tunes are awsome... i also have the k&n intake system and dual flowmaster series.
i started adding performace parts to my truck to improve my gas mileage but it also run's 15.6 in a 1/4 mile and now i am getting 23 mpg. i am planning on adding some gibbson or nissmo headers in the near future if anyone has any opinions.
