ISX 871 525hp No throttle response

[Biglentil]

Just an update everything is back together hollowed out dpf canister, tig welded up egr cooler exhaust passages internally with a couple stainless plugs. Not the prettiest stack of dimes welds ever but not bad will do. Replaced Imap and Exhaust back pressure sensor. Broke middle pin of delta p. Cut a copper plate to block off venturi tube from intake. Was tempted to remove the venturi inlet that extends into the intake, looks like a restriction point. Have the filterless insert in my crank case filter location. Inline 5 came from China I have software installed but am waiting on the password. Off to the truck boneyard on monday to strip the outside temp sensor and wiring harness out of an damaged aero mirror. Mine was butchered by previous owner and is MIA . Kenworth says two weeks if ordered through them. Can I start the truck just to move it outa the way before the tune or bad idea?
