2008 1500, Quick Performance Upgrades?

[Lynx]

Hey, was just wondering if any had any ideas for some quick upgrades for my truck. All I have really looked into so far are cold air intakes. Any and all help is appreciated!

It has the 5.3l engine with flex fuel.

Best bang for the buck is http://www.pcmforless.com/, http://www.wait4meperformance.com/. I would stay away from the hand held programmers. There not bad, but they still have limitations to how much tuning you can do to your ride's performance.

Look at these...........

I had a 2008 GMC Sierra with the 5.3, I installed a throttle body spacer, Airaid cold air kit and an Edge Evolution programmer. Really woke the truck up. Beat my buddy's Dodge Cummins with the Bully Dog system. I sold it all to my friend when I got my new truck. But all in all, great performance and increased fuel mileage, even in "extreme" mode.
