I recently bought a 2006 F150 Roush Stage 3 Supercrew. I have run a best time of 14.5 seconds at 94 mph. Here is my dilemma: I thjink that Roush left lots on the table when they tuned the engine. The 96 mph speed limiter is still in place and I'm sure there are other things holding it back.
So, what can a DiabloSport offer me? I like the fact that it holds 5 tunes as I drive it every day to work, have to tow sometimes, etc.
I'll post a pic soon.

you want troyer, from what i understand when it comes to the roush trucks he has them nailed down pretty good

 

Yes the roush calibration is conservative......your best bet is to contact Mike@ Troyer Performance....

 

The Predator or Trinity will allow you to modify the tune thats on there now, you can turn off speed limiter, adjust tires/gears, and even add a little timing at WOT or lean it out a bit if you so desire.
