I plan to in the morning. I sent you one on their other truck last year. IIRC they had it turned to 700hp from 565 and you sent a whole list of the mess it was. I kinda expect this is gonna have same stuff in it.
Plus whoever did it left everything intact, filters/egr etc. I don’t know how long they’ve run it like that. Thank you.
