Does it work?
Thanks

first setting take off and power was day from night difference and as a
bonus I got better mileage. It would break loose the dualies if you hit
the throttle hard( not towing of course) I sent it back to be
reprogrammed however because it caused the ses light to come on when
towing. It was making more boost than factory limits. I have never used
the off road setting because I don't want to endanger the transmission life.

Can't comment on that particular one but I do have some interesting info.
Last week a friend was in to visit. Until last year he was the chief engineer
for one of the major "chip" companies. We ended up chatting about diesel
truck tuning and he regaled me with trials and tribulations of tuning pickup
diesel engines. Combining what I learned from him with other experience, here
are some thoughts.
There is basically an unusable amount of power available from the engines used
in all three major brands. The tuning has been downgraded for various
mechanical and emissions reasons. For instance, GM had problems passing the
EPA visible emissions test which consisted of an 8 second wide open throttle
run while the exhaust opacity was measured. GM finally solved the problem by
delaying full fueling at wide open throttle for 8 seconds. That makes the
engine feel like a dog and is easily tuned out by the aftermarket tuners.
The problem is, how much power to allow. My friend was telling me about the
problems they had with the early GM diesel which had a weak head gasket. It
would weep coolant into a cylinder, cause it to score and seize, break a rod
and pop a hole through the crankcase. They thought they had a pretty good
tune worked out but when they gave a chip to an RVer pulling a large fiver to
test, disaster. The head lifted during a long WOT uphill pull, the rod broke
and popped a hole through the crankcase, the oil hit the exhaust and caught on
fire and the result was a burned truck and fiver.
The important point is this. If you go with an aftermarket tuner, you can no
longer just lay on the pedal and let 'er rip. The OEMs tune so as to protect
the engine and drivetrain against most any foreseeable treatment. They know
someone is going to load the vehicle right up to the GVW and head up one of
those climbs in the Rockys wide open without a thought or care in the world.
The aftermarket tuners of necessity, have to reduce these safety margins and
sometimes eliminate them. That means that you can break your toy if you're
not careful.
So yes, the aftermarket tuners do work but you have to be careful.

Like racing engines, which are drastically detuned in order to run for
the entire race :-)

That's funny <g>. I didn't know they cheat on tests just like some
computer hardware manufacturers cheat on benchmarks.
