Howdy,

I am new to this site and I would like some feed back on performance recommendations. I just bought an '08 Ram 1500 Hemi and I would like to know what upgrades work the best. I do not want to put exhaust on it because I get tired of the rumble. I replaced the air filter with a K&N replacement filter. I was looking on ebay for chips and there are tons for under $30 with unrealistic hp and milage gains posted. Do any of these work?

Thanks for your help.

Matt
