T800 using up too much fuel

[SHiggins3604]

I bought it with the bigger cam and already demandated but someone a friend of a friend modified the programming after I bought it and since then it's been using up more fuel. It does still have the VGT. I've emailed you the ECM file. Thank you for reviewing it.

What do you expect?... you (or someone) butchered it by modifying camshafts and other garbage. - What else has been removed/altered?. - And is the VGT still on it?.

And I can guarantee that the programming is both harmful and garbage-butchered into oblivion too if whoever did it even suggested that you put different cam, etc. in it.

Start by copying the program from the ecm and e-mailing it to me for a proper review of what someone did in there. - And also start sourcing parts to put it back the way its supposed to be instead of trying to drive it around with butchered components/mods that don't belong in it.
