Does any body know the amount of horsepower and torque the Redline adds . the website says 60hp and 100 ftlbs more torque than the FMS, but it doesn't say how much power the FMS adds

 

i think the FMS is compaprable to the Edge Comp, so I'd suspect 100-120 HP.

 

The redline is a really nice box! But in order to take advantage of the addition rpm you need to upgrade the valvetrain components. Springs and retainers are a must and if you can get a good set of improved bridges that all the better. but, be ware not all of the aftermarket components are equal. One popular diesel shop is selling sets as an upgrade that are actually lighter spring pressure than OEM springs!

I thought about getting the springs and retainers from enterprise engine are these alright and thanks for the responses
