trans question
 

to what horse power is the factory trans on an 06 250 rated

from what i have read is that your truck is rated at 325 horses and 570 ftlbs of torque

Do you mean how much will it hold? Who ever does the tuning and how it gets driven are the two major factors, but a lot of guys live above 500rwhp without issues.

im talking what will it hold...im gettin rdy to do an sct which i know wont hurt it but im thinking after i do the sct and headstuds im gunna get into turbos and all and i wanna try to push the mid 500s in hp
