F49 is the 15A fuse that feeds both VCT and O2 #1 bank 1 and O2 #1 bank 2. Bank 1 in passenger side and bank 2 is drivers side. Additionally The wiring harness connector number for bank 1 is C1571 and bank 2 is C1572. If these are reversed (commonly happens during turbo and LT installs) you will have extreme lean in one bank and extreme rich on the other bank. Additionally O2 #2 bank one and bank two are C141 and C142 respectively.
Not knowing the Hellion kit but assuming it is like most Supercharger kits the package comes with a larger MAF tube. So you are swapping the existing MAF sensor into a larger tube that is calibrated to meter air in a smaller tube therefore more air will reach the cylinder than the MAF is seeing and create a natural lean condition. STFT's and LTFT's will attempt to correct for this. The larger fuel injectors as well that came with the kit will also not be working on the correct data as again the car has not been tuned. 2005+ cars are not like the 2V 4.6 and below. On a 2002 you could swap out the factory air box for a "CAI" kit. THe MAF sensor in older models was mounted in a tube that transferred to the new CAI so recalibration was not essential. In 2005 this all changed. Also remember that in 2011 all front O2 sensors installed are now wide band sensors. They aren't the whimpy standard O2 sensors used prior to the Coyote so you have real data feedback from them.
Some guys have resorted to installing the O2 sensors from the F150 Coyote pickups...they have a much longer cable end on them and they do not require the extenders which have been known to cause O2 issues in LT applications from time to time. Sorry I do not have a part number but Mike Bell may happen to know that part number if you contact him.
Below is a link to a generic 2011 set of prints I used when I had my 13 and 14GT's. They give general oversight but remember that there were some changes in 13/14 that will not be the same on this set of wiring prints. However the concepts on this topic should not have changed.
BTW - If the fuse is blown you may wish to check that the extenders are not defective. A short to ground in one of them would pop that fuse as quickly as the 12 vdc feedbus common to both the sensors and VCT would if it were pinched to chassis ground anywhere.
To verify the +12vdc voltage bus for that circuit if the fuse is blown, remove F49. Use a test light to find which side of the fuse is the 12vdc supply. The other blade slot will be the feed bus to the devices in question. Use a multimeter and check the resistance on that blade slot to chassis ground. If you get a low resistance of 2.0 ohms or less you have a pinched wire or some form of direct connection to ground. You should read some resistance as you are reading across VCT solenoids and the Or sensors. But it will not be 2.0 ohms or less. It will be quite a bit higher. I would expect 120 ohms at minimum up to several kohms.
