im in full agreeance with snoopy, because the ems that has to be used to get down the high idle probles and idle surge problems and fuel to air ratios is the aem ems, its the only ems strong enough to handle itbs CORRECTLY. All of the other ones dont like itbs. Anyone who isnt going all out, will look at the cost of ITBs and something to run them and will think, wow theres an air intake system thats the price of that turbo that I was gonna buy... which one is gonna net the most gains.
