So, I'm with Rol on this whole chip thing. I'm seeing alot of post regarding chips and high exhaust temps. I understand with some of these performance products you have to change the air intake system and exhaust when you make the modifications. I have a 4in stock on my 2006 Dodge Ram 3500 5.9L -3rd gen Mega DRW pickup. My truck is not concerned with fuel prices or a recession :smiledown: It does fantastic with a Bully Dog Power Pup for power, but no change in MPG. Does anybody out there have the secret formula? Suggested was Smarty Jr, MBRP exhaust and AFE intake.
