MSD: Digital Propane Injection
Anyone tried the product?
They claim it works well w/ tuners and adds up to 70 HP. It also increases the range of the vehicle (assumably because you are burning 2 sources of fuel and measurimg MPGs off diesel fuel alone)
Is this product for efficiency, lower EGTs or increased power?

Customz,
It's actually for all three. It's gets the average diesel 60-80 HP, increases MPG (if you drive like you want MPG anyway), and cools EGT's 100+ degrees on average. It's also the only system that allows the user to reprogram the propane curve based on what "other" mods they have or don't have etc. Quite a product overall.

Now I'll buy the power gains, it does add a good kick...
But as far as lower EGT's, the BS meter is creeping up here...my TorquePro most certainly does not lower the EGT's, and I have never seen nor heard of any propane system that actually does. Logically, it cannot. People seem to have this misconception that propane is a catalyst with diesel fuel- chemically, it is not. The faster burn rate does assist with burning off all of the diesel, but you are still adding fuel- more fuel = higher EGT.
On a good note, of all the propane systems, this one does appear to be a very quality product.
Vic, you got any input on this one?

look at the notes under the picture of the system it states to install a pyro guage as exhaust temperatures increase.

If you do not use exorbitant amounts of propane to accomplish what a small amount will do, which is simply help burn the diesel that is present more completely...., then yes you can actually see lower EGT's. .
Now mind you, this is not a tremendous drop by any means, usually only about 50-100 degrees but it should not cause them to increase.
And yes, you are correct, propane is not "technically" or by definition a "catalyst" in the true sense of the word, but for lack of a better way to describe it's effect on the diesel fuel, it is used to explain what happens.
So while you are adding a fuel, the key is to not add a lot, (i.e. control the amount) so that you burn it (the propane) completely and more of the diesel along with it, such as with a system that is variable and controls and meters the flow of propane by a constant perimeter such as ...........boost pressure
Gauges are a good idea, regardless.
