Okay deleting all these things is not good advice,it also is illegal although the chances of getting caught are slim,but the fines are big,that's gotta be fun. I don't know why people think exempt from testing is the same as legal to remove. The police aren't going to come in your house and inventory your guns. Just because the police aren't going to inventory your guns,doesn't mean it's legal to modify them for full auto. Big difference between no inspection and legal. You're egr allows you to run more timing for more mpg , also partial chamber filling with inert gas for more mpg and less preignition chances,and also cooler cylinder temperatures.The Evap system keeps your fuel from evaporating so you get to burn all of it, instead of some of it while the rest evaporates,also since it keeps the system sealed you don't get as much water vapor in the gas tank.. The efe heats the intake when it's cold to aid cold weather drivability ,and a hot intake gets better mpg. The pcv keeps oil leaks down and helps ring seal,for more power and mpg. The hot air door on the air cleaner again hot air on coldstarts for better cold weather driveabilty,hot air makes more mpg than cold air,these are all scientifically proven. And last but not least warm intake from efe,warm carbureator from hot air,the choke can open sooner,again more mpg and less fuel wash on the cylinders.
