My truck has done this since day one dont know if its suppose to though...
When i first start going if i put my foot down it seems to bog downuntil about 3200 rpms my speed increase and the rpms go up but it seems sluggish. Any ideas?

I have a k&N cold air and exhaust not sure if that matters.

 

nobody has any idea?

 

Ive got the same problems in lower gears on both of our trucks. I figured it was Ford's powerband, but I kinda hope that isnt true.

Is yours doing it in gears higher than first or second?

 

unless i get the trans to shift a little, i think its because i have 33in tires so i might need to re gear

 

You shouldnt have to regear with 33s. have you replaced your spark plugs, cleaned air filter, replaced fuel filter?

 

Did spark plugs a little after i got it so less then 4 months and fuel filter was done a couple months ago and everything else seems fine. It may just be me, i have the E4OD trans dont know if that helps at all
