I know its been asked before but I can't find it. Is there a power programmer available for the 2004 4.7?


Also, I'm looking on ebay for a flowmaster 40. I'd like to fit it on my stock exhaust. What's the diameter of my stock system? ( I'm currently working living away from my truck and unable to see it )

Thanks for all the help.

 

I'm pretty sure there's not a chip for the 2004 4.7 not sure why
