turbo motor runs great until vacuum lines are hooked up
My 5.3 is finally done new turbo finally mounted and it starts great runs great idles good but when I start hooking up vacuum lines it starts to big be sluggish and runs rough unless I unhoom the charge pipe it gets a little better but not much it has a start up tune but not a dunk tune yet will this solve my issues or do I need to figure this out before hand it's a speed density setup with both front o2 sensors hooked up I just want to be where I need to be before loading up and heading to the dyno it's a fuel injected stock pcm motor no mass air meter
