GShelby09 Posted December 29, 2013 Report Share Posted December 29, 2013 I have a 09 5.4 Supercharged and I have see a few cases where guys add the Hellion TT Kit and it goes perfect with the stock supercharger. Just wondering has anyone done this and if so were there any other upgrades you had to do and how much more power did it produce.
