Hello folks.. Dodge Noob here...

I am an import tuner and know little about big domestic engines, however I am an expert engine management tuner(primarily Hondata and AEM) in the 4 banger world... A good friend of mine has already installed a K&N Intake system and an aftermarket exhaust (not sure of the make, but it is a side exit setup, which dumps right in front of the rear wheel), and is exsperiencing a degredation in both performance and fuel economy (as I exspected).

I suggested that he seek out some sort of engine management, to correct the AFRs, to match the "upgrades". Any suggestions?

Thanks in advance.
