Hi I was wondering if anyone knew what size injectors are currently in my 2008 F-150 supercharged 5.4L Foose edition. I want to upgrade them but not sure to what size. Any suggestions would be appreciated. I plan on putting the smallest pulley I can on and also Underdrive pulleys to get the most out of the supercharger I can. Also want to change out the air flow mass sensor and get a tuner that would help. I've contacted troyer performance and now awaiting a response. Let me know what you suggest and why it would benefit the power output on my truck.

 

Only an Ijadit blows up a completely sweet running rig to alter a Foose. Sorry but no is the answer you are looking for. It will never be worth more than as it is from the showroom. Trade it for a new EB of your liking and upgrade it with warranty approved stuff. LOL

 

Ignore the ignorance posted above. There's plenty of safe power to be had in that truck. Your Saleen kit is only pushing 5psi. Even Roush pushed 8psi and maintained the trucks warranty. Right now you probably have 330-340 to the wheels. I'm guessing 39 or 42lb injectors. These are good to a max of 450rwhp. Upgrading the Saleen can be a bit costly because of the crap you have to buy. Inlet tube and air box suck for one. But other than that its the standard pulley swap and retune. Need some details to be of further help. So.....
What size is your current MAF housing? Btw stock MAF sensor will support 450rwhp. The housing size is important.
How much boost do you want?
What are your hp goals?
Exhaust mods?
Any other details will help. Mike Troyer is an awesome tuner. See the link in my sig.
