My buddy and I both have llys, his is an 2004.5 and mine is a 2005. he is worried something is wrong with his truck. I have LBZ intake and mouthpiece and the maf is been flashed. I also have 4 in from down pipe back no cat or muffler. his is stock. I have 185 75 16 and he has 165 75 16. Mine pulls quite a bit harder then his, even though I have bigger tires. Will these mods make that big of a differance. or could he be having a problem. His truck is smooth, starts great and gets 18 mpg on the highway. I think his truck is fine. just looking for some opinions

The exhaust would make quite a bit of difference with no Cat or muffler.

I don't think your buddy's truck has any issues if it performs like that. Opening up the exhaust and intake will really help a truck's pep. If I were him i wouldn't be worried.

Sounds like its working fine to me. Thats about how mine ran prior to getting rid of the cat and muffler and putting on the 325's.

we put a mouthpiece on yesterday, not much difference that we can feel. we have the lbz cold air intake but need the efi to flash ecm before we can put it on. I will hopefully be ordering efi live for both of our trucks today, from Dustin if all things work out.
