you dropped a K&N in there, added Bosch +4's
(

) and got nearly 25hp over stock!!!!! WOW!!!
Your modlist of "really extensive" mods, needs to be changed.
get rid of the BOSCH crap plugs, use autolite APP764 double platinum plugs.. BOSCH = CRAP (99.99999999999% of the time on this car)
For wires, go with OEM Motorcraft 8mm, Magnecors if you want to spend more for max performance.
