2012 F150 FX4 supercrew, 5.0. Have had the roush blower on it for some time with their weak arse warranteed tune. Had american racing headers and magnaflow catback installed, along with a smaller blower pulley to up my boost. Installer custom tuned it after it was all said and done. Sitting on 488 horses and 450 ft/lbs of torque at the wheels (he estimates 612ish hp at the motor). Pretty fun, it'll run.
Ive installed a few of the roush superchargers. nice setup.
just put a whipple charger on my buddies new mustang its capable of 40lbs boost. only running about 20 now til we get it on the dyno. hes waiting on some new 60lb injectors so we can light the wick.. should make close to a 1000hp when cranked up
You would be surprised just how much improvement you see from tuning alone. There so many bull shite "safety" things on these motors these days. Mine for instance, i was told, would only go half throttle no matter how hard you press the gas below 4500 rpm. That along with the torque management really robs alotta of your stock power/responsiveness.
