i put $20 of 87 fuel today... it just a tad over a quater... and my kota has been burning fuel alot more lately idk y... i changed the plugs last month to ngk resitors... and i also am running a twin cold air intake that sit under my scoops... and not only am i losing fuel but power lost also... i am running a superchip at 87 octane preformace mode... well just tonite i did a canyon run and i would say it was a good 30mile round trip and im sittin on empty now

i have a 4.7 with all mod above its 4x4 if ran it in 2wd mode and the canyons where all pavment no off roading.. any ideas y its wasting so much gas and lost power???

are you using the same gas station as before?
check the ethanol content percentage.
is the air temperature higher now?
have you checked tire pressure?

i have no idea if some of these will even affect, but they're a start.

could be a number of things but my initial thought, heaver foot. if may feel like a little less power due to just bad gas or higher summer air temps/humidity so you are compensating with more throttle. I would try running 93 octane and stay off the gas and see what happens. It's also possible some of your mods have changed things in a negative way. Double/trippling the amount of air being pushed into your engine may not be a good thing if you aren't running a cam and could effect your low end TQ causing it yo feel sluggish and making you push the gas more.

I was thinking that it might have also been the altitude up in the canyons that might of effected it... but idk tho...

Set the cruise control at a highway speed and drive for a while to see if the mpg changes. Also check the fuel lines, maybe you have a small leak that you don't know about. Lastly, check all of your sensors as well, something may be causing it to not like the mods you've done. Lots of reason's for poor gas milage.

Just a thought. A bad O2 sensor can cause engine to lose power and consume more fuel. So can a clogging cat.
