Of my mods to date, I would rate in order of usefulness:
What do u mean by air box mod? Is there a DIY mod or you mean just a CAI?Think it was something like that
1: Headers
2: Torque Converter
3: Tuner
4: Cat-back
5: Ported TB
6: Airbox Mod
If I wasn't waiting for the Whipple kit to come out, 4.56 gears would be next on my list. From the other feedback I'd read it will likely be one of the best mods you could make. Even with 4.10's the truck could definitely use better gearing. Obviously the Whipple kit will surpass all other mods by far if you don't mind the 8k+ price. But their last response to my inquiry was, "Hello sir we are still waiting on casting and a few other things to engineer."
The torque converter along with Hemifever's trans tuning did wonders for drivability, so highly recommended. Along with a gear swap it would probably the best way to start. The headers did drop my 0-60 about a second, which is why they are high on my list. One good look at the factory log manifolds and you can easily understand why they help so much.
I didn't feel like digging up an old thread do I figured I'd ask it here. Did you end up blocking the stock air inlet ever? To me it would only be worth it if I ended up doing that and it would be kind of like a poor man's vararam. I've got the hemifever tune, mufflex, Moe's TB and k&n drop in and the next mods are a little rich for my taste so I've been trying to find cheap mods like this and possibly replacing the stock intake hose.
