I have recently purchased a 2004 F350, CCPSD,Lari 4x4. It has appr. 112,000 on it with the Magnaflow turboback exh, EGR delete, and new head bolts. I know the man I bought it from and has taken good care of it. He purchased the SCT when he got the Liberator EGR delete, but didn't install it based off of his Techs concerns with chipping the 6.0L. Anyhow he offered me the SCT 200$ I think thats a far price and I've considered it just a little nervous not knowing what type of head bolts where installed. Any suggestions would be greatly appreciated.
