well I think my hyperpac left something on my pcm. I double checked to make sure every setting was put back to stock on the hyperpac and drove it for a week like that. I bought a used gryphon off an f150 online member that was set at stock and it says checksum failure. I read on here that bill can rewrite the factory setting so i'll have to check into that. I want a custum tune anyhow so maybe I can do it at the same time. thanks Brent
