The Power Commander is the best fuel management system for the Warrior however it does require a custom mapping process to be most effective. If you want to go cheaper with a Plug N Play device I've got a used Cobra Fuel Processor in the classified sections that I'll sell for $75 shipped. It's got three adjustments for idle, mid-RPM, and high-RPM. I bought it when I put Bigshots on a couple of years ago.
I used it for a year plus with good luck, then I started doing more engine mods and just decided the PC3 was a better option for me since I had more complex requirements than just the Bigshots.
Here's the ad in the classifieds if you are interested.
