okay something weird is going on i got my car running last night after working the bugs out of it, the new engine has new pistons bearings, emissions removed, slowboy boost controller. When the car start you have to keep your foot in it to keep it running and it stumbles and spits. The higher it revs the more vacuum it makes and it will never build any boost any ideas suggestions
