I have an 07 with the 6.7. I have just added an H&S Minimaxx with deletes, and was wondering if the boost fooler worked and was worth the money. It seems to be pretty cheap and easy horsepower, if it does. Just wondering if anyone had tried it. I have to say that I'm not really sure what it does, but I'm assuming it controls the waste gate?????

 

I bet your minimaxx all ready has and does this...
