Anybody with the same situation? Also the main question I have. Say, when you go try to do a boosted launch. I can't rev up the truck or build boost if its at a complete stop... is that normal? I have to roll into it. Let the truck creep a few feet forward in order for the RPM's/BOOST to build. its like its surges if I'm at a complete stop and falls flat on its face.

If thats not normal... Can I do some data logging and maybe get a fix?
Are you sure the line pressure is jumping up? If so- whats it jumping to?
