My dad has a 2002 F-250 4X4 with the 7.3 litre POWERSTROKE diesel. He wants to buy a programer to get more power/torqe/gas milage....
He has looked at the diablo programer. Is this a good choice? Is there a better one out there? If so.... What and Where? 
I hope you guys can help me to help him with a wise choice... THANKS!
EDGE ALL THE WAY!!! The rest are junk!!!
