Maintain He wants a predator for a towing tune and a cat back 4" mbrp he has a extended warranty on the rig and is worried about that so he doesnt want to straight pipe it. The truck only has 11,000 on it its a garage queen it only pulls the 36' jayco fifth. What tranny stuff you talking about ive also talked him into pyro and boost guages.Some of the tests ive seen says the best CAI they have found is AFE flows 20% more air but am i correct in thinking the turbo is only going to take in so much air and put out so much Thanks
