any ideas?
 

I just put brand new injectors in my 05 yesterday and i went back to the stock ones for now but for some reason my computer that calculates the fuel mileage went down. Why would new injectors cause mpg to drop?

Are you 100% stock right now??

nah i got a puck and a boost fooler and k&n

Take the puck off, or turn it down. Also driving style??

New injectors flow better than old ones!

i run it with it off. i just have it for when i wanna play around.

thats what i was leaning towards but i was wantin a second or third or fiftieth opinion lol. thanks

have u hand calculated ur mileage yet?? when i replaced em in my old 06 the overhead went down but it was actually reading accurate not 2-4mpg off. could just be that now with the new injectors ur actually getting what the overhead shows too.

just got my injectors changed and I'm having the same issue, my mileage has gone down at least 75 miles per tank.

well i filled my truck up yesterday and hand calculated it and granted i do let my truck warm up some still but it dropped down 14.5 mpg. do you think maybe air intake time or what?
