power programmers

[alabamakayaking]

I just bought a 07 Tahoe it has 6 a inch lift setting on 35's. It
started out as police car in Tennessee. I think someone bought it and fixed it up
To sale it's in great shape it has 149 k on it. my question is about power programmers
Not so much worried about performance as I am MPG. Looking for some suggestions for the
right programmer

I have a bully dog gt tuner.. It really made the truck come alive, as far as gas mileage, I've noticed small gains but nothing to really write home about.
