The SPE 7.3L Powerstroke Boost Fooler is an electronic controller that limits the amount of boost the computer can see, so that you don't get a check engine light when boosting above 22 psi. Includes everything needed to install as well as instructions.
Extremely simple installation.
We have used this instead of the old mechanical regulators for years making well beyond 700hp.
*These are solid state and never need adjusted so there are no mechanical parts that can fail*
