what is the MCP hose on the truck ?
Dealer said our recently worked on 06 f350 had "carbon" in the mcp hose and intake manifold valve or something, that was the reason suddenly the truck would make zero boost and threw a code...
Truck just had $8k in work done to it, egr cooler leaked, blew head gaskets :/
Got arp studs put on, garrett powermax turbo charger unit, 21mm ford head gaskets, new oil cooler system, Bulletproof diesel stainless lifetime egr cooler added.
Truck ran "ok" from dealer, my buddy "tuned" it? but not like an sct or added anything, im not sure what they did, but it added fuel b/c truck finally felt faster after ford fixed the truck with all those parts.... then after this $260 in work with a mcp hose clogged with carbon...it runs ok, has boost but slow as a mofo again.. My wife drove this truck bone stock and after the turbo/studs, egr change it had no pickup.. after my buddy fixed the pcm,, was good again... now its not throwing a code and has boost but slow as a mofo again? whats going on?
