how does this affect rear end gears and mil eliminators? Does it have any specific advantages such as speed, 1/4 mile time etc.. Help Me!!!!

 

only really useful if you have an auto,and you changed your gears. need the programmer to recal the speedo( as far as performance goes) to save money if you are only wanting to change your timing for that few extra hp it would be more cost effective to get the Steeda Timing Adjuster ( $160.oo or about there vs. $350.oo-400.oo) just my 2cents tho

 

what about air fuel ratio, and cooling fans and downloadable programs.

 

There is a huge section of information on Diablo programmers at www.modularfords.com I know its another mustang forums but they even have the company vendors there to speak with about that product very cool
