So I finally ended up with a chip but I haven't purchased custom tunes yet. Horrayyyy get to add that to the signature

 

So I went n shut my Egr off n my p0420 n p0430 codes haven't came back so far, no check engine light

 

What tunes you looking at getting and from who?

 

I'm not sure where , my buddy has a diesel shop n c n if his connects can do gassers but deffinetly want the max for 91 . I was hoping the chip out of the box adjusted for injectors, exhaust n intakes but only certain models , not these guys darnet, pretty much diesels n mustangs I guess . So I'm saving up that $100 for the customs

 

MPT has tunes starting at $75, you can get 3 for $150

 

Stll waiting for some extra cash for tune but I'm noticing better fuel, still running rich but codes haven't came back after shutting off egr
