Bully Dog claims to have the lowest EGTs.
Superchip claims the same danged thing.
Hypertech says they are the easiest to use.
They all cost just about the same ball park number, so I could care less
I have an 03 Ford F350 PSD 7.3 liter that I am considering chipping or
programming. My main reason is my fuel consumption. I hear claims that
people can get 21 MPG on a bully dog chip. I do not need the horsepower. I
have plenty of torque. Would I like more? I'm a man. Do I need more? No.
I understand that any fuel savings will come after I get over the initial
excitement of the increased power. But I expect that will be short lived,
as I do not make a habit of racing the kids at the stop lights.
What I am looking for is a comparison of the various power programming
devices...chips or tuners or downloaders...whatever. I am confident I can
install any of them. I've read all the install instructions. Most plug
directly into the OBDIII port. My computer is easy to access if I go with a
I just want to know who has what and what your results have been. Any
reason why the manufacturer's engineers feel the stock computer should not
carry a program that causes the engine to reach full potential? Warranty
issues? If I chip it it will be hard to return to OEM specs for a service
visit. Is that important? I do not want to blow my motor or burn up my
tranny. But I sure would like to save some money of fuel. I currently get
about 12.5 hand calculated MPG.
I also know a larger exhaust pipe and new filters could help. I plan to do
both as well as add some gauges to monitor the engine.
