When I bought my Class 5 last year, the 6.7 PSD was putting out 300 hp and the 6.7 CTD was putting out 325 hp. What is interesting that they are now offering three different tunes for the Class 6 and 7 trucks. Seeing the low numbers in both Ram's and Ford's real working trucks just reaffirms to me tuners are for mall crawlers and racer boys - Not for people seeking a reliable working tool.
Most FICM issues in the 6.0 PSD were due to insufficient input power delivery due to low/weak batteries or poor contact at the connectors, although some failures were traced to ambient heat issues. EGR or oil cooler failures require replacement of both units to prevent cascading failures. What I have just written about the 6.0 has been well documented since at least 2006 and there should be no excuse for any shop to do only half the repair job resulting in repeated failures. Although there was Ford tune on the this engine, it was not their design. I doubt any of the 6.7 PSD shares components with the earlier engines.
