Boost Fooler

[99BEIGEPOWERSTROKE]

I need some type of boost fooler for my truck. It will set the check engine light of if I really get on it and have about 22 lbs of boost plus and defuel. Can it aslo defuel even if the check engine light isnt on? Say I only am at like 12 pounds of boost could it defuel to while driving? What boost fooler is the best for our trucks? I have posted three I was looking at which is best or is there a better one out there?

Do you not have tunes with your injectors and turbo? i hit 25 no problem. if you get good tunes you shouldnt need a boost fooler..

Oh I can hit 30 lbs of boost easy but it sets of check engine light and the boost fooler prevents the check engine light.
