So what if you don't want to buy a '15, but you want to have more power than a '15 does?
Then you learn how to build that, and that's what this thread was supposed to be about. And it can be done.
The guys who do this don't care about warranties. We don't go to the dealer and wait weeks or pay crazy amounts for something as simple as slapping in a new lift pump. We just bolt it in and know it was done right. Amazon can get you one in a day, so can places like Genosgarage.com.
About the gears, I have 4.10s and a Gear Vendors overdrive that effectively makes them 3.20 when I hit the switch. Under a heavy load, 4.10 is a lot better even with a lot of power.
But I'd say if you have 3.73, that might be a pretty happy medium... do you pull hills with enough weight that your truck feels like it wants lower gears?
