Which is best for the 2001 7.3.. I have 300k on motor and about 30k on billet built 4r100 tranny. I dont do much pulling with the truck anymore i just drive it daily now. I had a superchip micro tuner on it and pulled it off, before that i had a diablo chip in it and pulled that out as well. Looking for something that will give me more power as well as eco. soon to do a turbo upgrade to go with the new 4" mbrp turbo back exhaust. lol funny thing is that i put a muffler on it but it is not functional at all as i have ran a pipe thru it for better sound.:sneaky::ford:
