Yes I have the spartan and i have read the codes but everything is okay. The truck is still getting around 14psi and that is what i was getting when i was stock. Once i put the tune on i could easily hit 35psi. I understand that 14 psi is going to be better for the life of the turbo but the thing that i dont like is before the crash and them putting a new frame in i did hit 35psi and after i only hit 14psi. Thats why i think that maybe a connection for the "second stage" turbo was not working. The only problem is the 2008 Fords you can see anythin when you look everything is under something. I can argue with insurance that it was their fault when they worked on my truck and i know they will pay for all of it to be fixed i was just looking for a answer so i could go there and make the time i dont have my truck as short as possible. Also if i did take it to Ford i dont think i would be in warranty since my truck has 60,000 on it and i have the spartan tune or am i wrong about that?
