allright finally moved into newer truck, bought y2k 4x4 dually club cab 6spd ctd of course, 1st of all seems like it don't have as much power I guess what I mean is on my 12v when you stepped on it it felt like you were doing something this you step on it and you get going but just not the same, yet its rated better in hp & Torque, also what are some simple mods have guages on the way one other thing I forgot just bought this truck two days ago used it to haul a 93 jeep for about 500 miles across the state of il. ( all Flat) got 11 mpg can't be right?

 

Check your fuel pressure to make sure your lift pump is working to its capacity. Thats the electric fuel pump that provides fuel for the inj. pump. that could explain why the lack of power and low mileage.

 

I'd change all the fluids and filters, unless you know FOR A FACT that they were changed very recently prior to your purchase. The clogged/contaminated fuel filter might be the reason for for the low power/mpg. Also, the IAT sensor should be checked/cleaned if need be.

IAT sensor? where is it? thanks guys!

 

Here is the how to.

Might try reseting the APPS also, that can make a big difference in response and full power.

 

mine was at 9.6 mpg I changed the fuel filter and got 14mpg then put in some inj cleaner/cetane additive and it went to 16+ around town

 

i've got that truck with 4:10's. hauling the rig in my photo gallery at 70 on the flats I get 7.

 

well checked psi today not good if I did it right there is a preasure tap on off the vp I checked there had 5 psi and then seen the other port before filter had same took pump out to see if it was dirty, nope must just be worn out replacing tommrow hope to see a new truck what do you guys think?

While you are in there it would be a good time to put some high flow banjo bolts in there. It will help your pumps and give you about 3psi across the board.
Just my $0.02 worth.
