Ok so I bought my wife a 07 Yukon with 107000 miles on it. We've had it about two months now and we are real happy with it so far except that it seems to be consuming oil. I read on here that this is a common problem with the 5.3L engine that's in it. I'm the type that can't leave anything alone and my wife could care less about it as long as when she turns the key and buts it in drive it goes. I ordered a Airaid Jr. this morning and been looking at ordering a Magnaflow 12589 muffler and deleting the resonator. I would also like to get a BB tune and eliminate the AFM with the hopes of reducing the oil consumption. The Yukon is a daily driver and I'm not wanting a race car but just want to do the basics to get the best out of my Yukon. Am I missing anything or should this do it ? Thanks
