So, on my 2007 2500HD classic with a 6.0, I need some ideas on upgrades for power and or fuel economy. I have $2000 to spend on upgrades and want to use as much of it as possible. If you all think I can't do much for that amount, then I'll just upgrade my stero system. But my fuel economy is low 6-8 mpg year round and I want to either improve that, or see some significant power gains at the least. Or, if you have an interesting and unique idea I could pull off, let me know and I might do that. Thanks guys, look forward to hearing your replies!

Exhaust, intake, headers, custom tune. Somewhere up to 50 hp and 2-3 mpg more than stock. Drive and have fun
