I've been told that if I put a CAI and Magnaflow catback on my truck it may lean it out too much. Is this true or do I need a tuner? Thanks for any help!

With those mods no you should be pretty good. When I put my 6.2 on the dyno with stock intake only mod was straight pipe and a can hypertech tune and I was running fat at 14. We pulled the air filter out and she dropped to 13. I want to lean mine out for the street but with my heavy camper it needs to run fat.

Shouldn't be too lean.
