Default needd a new mod! any ideas???

so im looking to start off 2014 with a bang and add a new mod to my truck. i dont want to go too extensive as in supercharger, force induction or nos. But i know you al got great ideas out there! any feed back would be great!!

here is a list of what i have done PERFORMANCE wise:
moroso catch can
180*tstat
v6-efan (clutch fan delete)
s&b CAI
flowmaster 40 w/resinator delete
trinity 91 pef tune
(sonnax lpb which i recently removed. think after the trinity i was getting too much pressure which resulted in a very harsh downshift from 3-2 and 2-1. any insight on this would be great as well)

im guessing everyone is going to say a ported or true tb. ive read up a bit and dont think i have enough mods to go any bigger then an 83mm unless anyone can convince me an 85mm would suite me better, i just dont want to hurt my low end performance.

also new headers is something i have had my eye on which im going to post in the exhaust section about but any info would be appreciated. arh or sw... high flow cats or not... 1 1/4 or 1 7/8 primaries...

here is a pic of the truck since i know all of you love pictures!!!

I just installed the Vararam on my '13 and absolutely love it, very noticeable increase. Pics are in the 2013 forum.

From what I have read I would go with hemifever over white lightning. Some members had transmission issues with the white lightning tunes due to transmission tuning. ( I believe) Hemifever doesn't do transmission tuning with the basic custom tune. I am sure someone here will correct me if I am wrong. I also have read nothing but praise about the hemifever tunes.

If you are going to change the gearing and have everything opened up, I would suggest at least the 3.92s. My plans are for the 4.10s, but for your situation I don't see why you would change to the 3.55s. I currently have them and am wanting something higher.

Hanks for the feedback ! I just recently swapped out my k&n for the new s&b intake. Performance wise it won't stand up to the vararam but I travel down a lot of dirt roads so having an enclosed box was definitely the choice I needed to make.

One thing I've never looked into is gears. I'm totally lost in this subject as far as what ratios means what and whether their best for speed or towing. Does seem 3.92's are pretty popular but staring at them their just numbers to me...

Possible lift or level with 35's might be in the future

If you are going with a lift/level and larger tires, your truck will seem like it has lost a bit of power/speed because of the extra weight. The 4.10's will give you more low end power than the 3.92s and are good for towing.

With that being said, the 3.92s will also do the same compared to your current ratio. So if you are looking for bottom end performance as well as better towing, either of those will do you justice, but the 4.10s will pull harder/stronger. They will also lower your MPG average compared to your current set-up, but depending on how you drive it realistically shouldn't be anything major.

Your first post said you want low end performance, so I stick by my opinion of the 4.10s.

Thanks for all the info! Based on your input and everything else I've read I think I'm going with 3.92's. If I do a lift/level it won't be for a long time and I don't want to hurt my gas mileage to much so I'm going to stick clear of the 4.10s for now.

Btw I stopped at my local dealer today to get an estimate and waiting for a call back. Will let you guys know how it goes!

No problem. The 3.92s will definitely be a step up.

Let me know the estimate, so I can get an idea of what it would be when I do it. I will probably take mine to a performance shop as it "should" be a little cheaper.

Are you going with gears from the dealer or did you find some online? I know Bully's sells some.
