Bully dog GT tuner
I installed a bull dog GT tuner on my 2008 6.4L .
I have seen an noticeable MPG acheived.
Someone told me that onstalling the tuner may invalidate my warrantee.
Any body have any more information on if that is so?
Alos just an observation. The GT tuner MPG tracker is like 3 MPG different than the stock one on my dash and it isa more accurate. So how reliable are the stock MPG meters?
