WOW,6000 miles on a Roush Supercharger Kit and a VMP TUNE and your 5.0 motor is still running?Come on guys stop the BS and hire a Professional Tuner like Kevin did if you want to mod your 5.0.I think Kevin is running a mail order tune from VMP TUNING.LOL+1
I will be turning 7000 miles soon, 6000 with the blower on it and the tune is hotter than the Roush tune. Granted I dont beat it to death every day but I do use it. Mine is also a may 2010 build so the 'early build' theory doesnt mean much. Obviously the regular 5.0 can handle more than 30hp, but not by just cranking more timing in and crossing your fingers it appears.
