Right now I have just a S&B cold air intake and was wondering what other upgrades can I do the 5.7. Since I have been working on the exterior look of my truck, I now want to focus on the engine. Any ideas would help!

Seeing as you have a 14,you still have one of the cheaper trucks to tune. Long tube headers and tune will make a noticable differance in power.Then if you still have any money left a ported 6.4 intake manifold.If the price of a set of ARH or Stainless Works headers sends you into sticker shock,guys are claiming the cheaper ebay headers are a pretty decent buy.
Helps if we know what kind of budget you have

The question I have is with the 6 speed, is it even worth messing with the engine. I hear people most people have the 8 speed and the 6 causes issues. Also I usually will just buy 1 upgrade at a time so the things u recommend I should be able to afford.

Its still very much a tunable platform. For about $750 you could get a tuner and a custom tune from Hemifever that would literally wake that truck up.
Simple bolt-on mods all add up to respectable gains. Dont waste money on anything until you get a tuner and tune except free up your exhaust.

The 6 speed is your downfall,it doesn't have a great rep once you start putting power to it.If you learn to drive it properly,it has a better chance of staying together,that means pre-downshifting it when you're moving,before flooring the skinny pedal,so when you're passing someone on the highway,manually downshift it first before flooring it,and no wide open runs in high gear either.The 6 speed is okay from a dig,it just doesn't like rolling wide open downshifts
You might want to check out the (2) 8speed swap threads on here,as it should maybe be your first upgrade.Guys are reporting close to a 1/2 second gain with the 8 speed swap,which is about what a set of long tubes and good tune will gain you


If you do consider a transmission swap to the 8 speed ,"do not" buy a Diablo tuner,you'll want to spring for HP tuning instead.

There is no way I’m going to be able to do a transmission swap by myself. That is way above my skill level tbh. I’m just stuck on what to do now.
