[QUOTE="Wrecker, post: 1519182, member: 12157"] The turbo shaft will almost touch wall to wall, not sure if that's normal or if as long as it doesn't touch and has no in and out movement then it's good. It could be the powder coat job, but the factory ford turbo boot is also starting to melt and deform a little, which makes me lean towards the temps actually being too hot. Also the midwest boot that blew, and all the factory intake and sensors that melted, leads me to think temps are way too hot vs having defective part after part after part. Waiting on Forscan to approve my account, I'm very curious what my secondary coolant temps are and hopefully it'll read ebp also cause I'd like to see what that is. Another interesting thing happened today. After I pulled the intake off the to check play in the turbine when I went to start the truck back up it would fire up and instantly shoot rpms up and settle at 1200rpm idle. I reved it up and it still wouldn't drop below 1200, put it in gear and then pack to park and back to 1200. Loaded a tune again, same thing, start up like your foot is on the gas and settles back at 1200. Went for a 20min drive and by the time I got back it was idling at normal 600'ish rpm and seems to have fixed itself. Seemed like what ever I did by wiggling the turbine shaft messed up something in the turbo and driving it for a bit got it back into place. Sure seems to me like exhaust gases are making their way to the compressor side which would explain the extra heat, why my boost reading is so jumpy, and why when I moved the shaft around it made it worse and was idling so high. I don't even know if this is possible, but that's just what is making sense in my head.....??? [/QUOTE]
