Most 6.0L programmers utilize changes to the ECM in order to achieve horsepower gains. However, ECM tuning is only part of the puzzle to restoring the performance and economy of the 6.0L Power Stroke. Ford's most current inductive heating strategy (which replaced the FICM damaging inductive heating strategy that was released in 2007/2008) resolves a number of cold start issues, but severely limits performance of the engine. With PHP standard ECONOMY FICM calibration, most customers see fuel economy gains as well as improved tip-in throttle response and better overall drivability from idle up through 3500 RPM. (We also eliminate that annoying injector post buzz.) However, PHP also offer fully modified FICM strategies that not only offer improvements in fuel economy, but also offer significant improvements in performance. With PHP's new ATLAS 40, ATLAS 80, and HERCULES FICM strategies, gains of 100 HP or more can be seen, even with a stock ECM strategy. Combined with a modified ECM strategy, considerable improvements throughout the RPM range can be achieved with significant improvements in low RPM and high RPM performance.
A frequently asked question, "Just how much difference will I realistically see by changing the FICM strategy?" Below are the dyno plots that show just what you can normally expect from reprogramming your FICM. The vehicle PHP tested was a 2004 F-250 2WD with 283,000 miles. Vehicle test conditions: Engine at full operating temperature, 3rd Gear, Converter Locked. To read the dyno charts, the Torque scale is on the left and the HP scale is on the right. This first image helps to illustrate the differences between a standard FICM strategy and a modified FICM strategy on an otherwise stock vehicle
