Bad gas mileage help



K all done antiseize used with new upstream o2....long term fuel trim still in the negs-7 to-17ish
With short term bouncing from +5 to -6....maf was cleaned as well.
 


So nothing to worry about?... I think i recall it being in the +'s a while back, both of them bouncing back and forth from neg to pos. I will keep an eye on the fuel level.
 




K i have that torque app. It says it has that reading for fuel pressure and rail pressure but dosent come up on the wiget thing. Are u familer with that app? I bought it so i have the full version. Just dont know how to use it fully.
It also has the maf reading in G/S. I heard theres the idle and throttle readings but dont know what they should be at.
 
Also i thought i had a trap door for the fuel pump in the truck if i did need to replace it but i didnt see it ...would it be under the back seat behind the driver side or do i drop the tank?
 
I've never used torque, but it won't be able to read fuel pressure, as there is no factory sensor for it.

And, I think 03 was the last year for the door to get to the fuel pump. Maybe some 04's got them too. But, I don't think 05 had them.
