Unhappy bad fuel economy, lots of mods????

96 crew cab long bed 2wd, srw.... only getting about 11.5-12 mpg
baby swamps injectors
cold air
straight pipe exhaust with 3.5" down pipe
terminator hpop
wicked wheel 2
as for tunes im only using an edge cts in tow safe mode currently
truck idles smooth, doesnt sound like anything internal is messed up, skinny tires, no lift, and driving pretty light on the throttle, ive replaced the cam position sensor, cleaned the ebps a while back, no oil leaks, or fuel leaks, what am i missing???? or do good tunes for all the mods make the package work???
