can anyone tell me what a boost fooler is and what does it do?

oldbeek

The boost fooler allows more than 20psi boost without throwing a code and cutting back fuel delivery. Tuners have boost fooling in them.

KATOOM

A boost fooler electronically bypasses what the MAP sensor recognizes and allows for more boost than the factory setting without throwing an overboost code. The wastegate will still regulate its preset limit too so you have to install a boost elbow on manuals which partially overrides the wastegate or on install a J hook on the auto's which keeps the wastegate from opening at all.
