have a 03 with just an edge easy i am wondering if a boost builder will do anything for me. i also have a 5inch mbrp and an s and b intake.

 

you can mess with the wastegate all you want. comes down to the ability to fuel and produce enough boost to reach the new wastegate settings.

 

It has nothing to do with the waist gate its all electronic..

The boost fooler will do nothing for you except keep the check engine light off when you are pushing more than 45ish psi. tricks the ECM into thinking it is lower than it actually is. With your manually wastegated turbo plus the edge, you are not pushing enough fuel to utilize one. waste of money and no power gains.
