i've beeing using the o/d off button all week @ 50mph. i notice a little more throttle response, thats because its reving higher.
but i got like 60 less miles on a tank of gas. thats 11.5mpg.maybe its because it has been 95+ a few days.

 

yea even worse in 2nd gear, 50 mph is 3100rpm but its got unreal throttle response

 

do i have the wrong gears then?(not 3.55) cause mine was 2000rpm @50 with the od off. and 1500 rpms with it on. this is cruising not mashing the peddle.

 

My last tank I only managed about 430km (~267miles)
this was mostly with the O/D off when under 40mph
Now I don't know if it's related yet, but i'm not sure my truck likes O/D off.

 

Mine was doing the same at 40.... about 1800 rpm.

 

2nd gear at 50 mph its 3grand

 

what about with the o/d on, is yours at 2500 then?

 

when i was in 2nd gear i had od on.

 

2nd gear, od on.

does anybody elses truck run that high? seems the engine is working to hard or something.

isn't the thread about how o/d off is so much better? im confused
