Hey Big Truck, I just put 4:56 gears in my 01 SCrew the other day and I'm running about 20MPH over! Gonna order the Troyer Tuner tonight , to correct the problem and give a bit more boost. Do you Know if this overage affects the odometer also.
By the Way I love the 4:56. My tires are 34" on 16" rims.

 

SNIPER= i think that the e fans do help alot in hot wethear if i was you i would wait till the summer to fork over the money, after the e fans i really noticed that it seems to cruise better, i think it is worth the money, i didnt really see a defrence in my mpg tho, throttle responce is better also

ZOFRO=yes it effects the odomiter also, when you fix the speedomiter with the tuner it will fix the odomiter also, glad you like the 4.56

 

I live up here in Big Bear and I think that it would be kinda nice to have the truck warm up faster too...As I understand, these fans wouldn't kick on until they are up to temp, so therefore it would warm up faster....Are they very difficult to install?

Thanks, I thought maybe I getting the milage of a Geo or Bug. Just from changing the gears.

 

sniper the install is pretty easy just time consuming, alot of electrical work cutting and splicing, use a soldering iron and heat shrink

 

My uncle is good at that stuff, I smell a favor coming on....

 

let me know how it goes and good luck
