[QUOTE="mustangc, post: 15238405, member: 87570"] Those results are mighty impressive. I can't wait to get one of these 5.0 trucks so I make this upgrade. The horsepower curve looks like it's still on the way up when the stock or even Roush tune puts a stop to it. The VMP tune sure confirms the engine has more to give beyond 5500 rpm (crazy low for a 4V). I wonder why the other two tunes limit the RPM when there's so much more potential there. Are they concerned about low octane fuel and towing, or damagining the torque converter with the higher input speeds? I wish someone in the know would be frank with us on why these types of tuning decisions are made. [/QUOTE]
