has any one had any problems when they changed an engine in thier ef ford. mine now has a street fighter engine from jim mock which cost a dam lot and wont rev up properly until 1900rpm from there it seems to rev up fine both in drive and not in drive. timing and cam angle has been checked and rechecked, throttle position checked, fuel pump replaced, injectors, everything ignition wise changed. cpu interchanged to another working cpu. i have been advised that it might be running lean ie not getting enough fuel. would this have something to do woth the fuel regulator??? this problem all started from after i installed the engine and not before with the old engine.
