well i just got 35's and 6" lift on my truck i got a true dual custom exhaust and volant cai plus a edge evo programmer. mpg already suck on 5.4 now its gonna get worse wat all can i do to get better power and fuel economy? im regearin to 4.56's in next yr or so(hopefully). i also wanna do some lt headers. i see a lot of power mod trucks have e-fans and wat not not very smart with mechinal stuff so any help would be nice thanks guys.

 

That edge programmer and the CAI are going to cause your truck to run lean. Get it custom tuned before you end up with damage to your truck.

Gearing will help, but you also need to consider you're running heavy mud tires on a 1/2 ton truck with a V8 engine. You may be able to squeeze 1-2 mpg out of it after doing E-Fans and gearing, but the best mod you can do is swap for some all terrains and drive like a grandma.

Or buy a commuter car.

 

haha thats like exceptin defeat cant do that but e-fans will help? thank you and wat do u mean the programmer and cai will do damage?

 

The programmer and CAI will cause the truck to run lean, which could damage your cats and o2 sensors, and cause you lots of headaches with the 5.4 down the road.

 

What he said


And there's a difference between accepting defeat and throwing money at problem you can't fix.

Like I said, get rid of the edge, get a custom tune, get some all terrains, drive like a grandma.

If you have the money left over get it regearded and some e-fans.

 

i got 35/12.50 on 18 inch rims 04 lariat screw 4x4 3.73 with a custom tune k&n intake and magna flow cat backs and i get 12 mpg but i dont drive like a grandma so u might be able to get a lil more

 

With 35" pro comp xtreme AT's (super wide and heavy) Stock Edge CS and Gotts, I was able to average about 15 mpg for the tank,

Getting some better ATs though as I do a lot of freeway driving

Send the edge in to power hungry performance and get it upgraded to a gryphon and get a custom tune also.......www.gopowerhungry.com

 

Get edge converted to gryphon,
Efans
UDP's

Go with an AT instead

 

I have the edge programmer and it works great for me!

 

Right foot mod.
