It almost feels if my throttle body isnt opening. I just added a high flow cat tonight (cold ad hell)due to local emission checks. I also picked up a vet servo which I will install when it's not snowing. My garage is to short so the truck doesn't fit. Everything I have installed has been outside in gravel after work. So it's dark/ cold and snowing when I'm working on it.

It is fairly normal to loose a little on the bottom end after an LT install. Like has been mentioned a stall and gears will make a big difference. Bang for your buck after a tune maybe the best mods out there.
