2011 silverado 5.3 predator tune
Posted: Wed Dec 04, 2013 10:00 pm
Hi all, I have had a U7194 predator for awhile now and have recently added a Airaid Jr. intake pipe with a drop in air filter and also put a 3" single in single out Magnaflow muffler/exhaust on my 2011 Silverado 5.3 Z71 4X4 with 6 speed auto. I have been running the canned 87 octane tune with DOD off and adjustments for bigger tires that I am running, Is there anything other things I can change on the predator with these new additions? I am mostly looking to increase my gas mileage. I recently updated the predator to version v.9r31. Thanks in advance.
