ok, ive got some extra money to spend and i want to spend it on my truck. so far i have this: 05' 5.3 with flowmaster catback and kn cai. i also tuned my truck with a superchips tuner. it has a 6inch bds suspension lift with 35s. i want to improve my setup and im open to pretty much everything (not nitrous though). ive been thinking about an lq9 swap and maybe an FLT tranny? im new to this stuff so any help would be great. i know this post is prob repetitive but i thought i would try anyways.

 

4.56 gearing?

 

start by ditching the superchips and getting a custom tune. Secondly get a built transmission. Those 35's are gonna kill your tranny. What gears do you have? You should also think about getting some lower gears.

 

Sounds like ya got a bit to spend. How about a supercharger? Like Magnacharger, for example. Then you'll have to get a custom tune with that setup. That'd be one awesome truck though.

 

+1 for the 4.56s, atleast if you start there, you will be close to where you were before the lift performance wise....
