needing info

[loki]

well i would like to start by saying sorry bc this is not a diesel by a 5.4l triton.

first i will start by explaining i went to the f 150 counter part site and got little to no help so i returned to the trust .org to see if anyone on here can help.
the 2 questions i got are
1- where is a good place to start mods and so mod options
2- are there any problems or issues with the engine or truck that i should be aware of
p.s. its a 2007 f-150 5.4L lariat super crew cab with a 5 and a half foot bed

once again thanks for any help or any knowledge i can get from you all
