so let me explain the situation. i have an sct livewire for a 6.0 and if i download the 7.3 software to it it will work fine. i know ts 6 bank chips r the way to go but this is one of those i already have it so im gunna use it till i can afford a custom tuned 6 bank chip

so my questions are have any of yall run these or know someone whos run these and know the true power and mpg gains of this. also my truck is an early 03 so its got PMRs do i wanna make sure this is safe for the truck (im sure it is but id rather be safe than sorry)

 

Should work fine. Not alot of people make tunes for it. I think Inovative does and Elite...

 

i probly wouldnt even waste the money tuning it. just run the canned tunes for some basic gains that im seeking and to correct for my bigger tires until i can get a ts chip and tune it
