Hey guys what's going on. I got a quick question .. I have a 2012 ecoboost and it does not seem to build boost in park. Is there a reasoning behind this or what to make it. Reason I have added blowoff valves and it will when your driving but not in park when revving. Thanks fellas

 

Boost only builds under engine load. There is none in park. All turboed vehicles are this way. Put it in gear and power brake it and u can build boost for launching. A two-step ecu tune can also allow you to build boost.

 

Ok..just a couple videos I saw had them reving in park and blowing off just wasn't sure but maybe has a tune
