New to 7.3 with a few questions.

First let me say I have searched and researched all the diesel related forums I can find and have found some great info. I still have a few questions. I just bought a 99 F-350 SRW CCLB truck this month truck has 225350 miles on it.

It has a 4" exhaust with no cat and it still has the stock air box. I have ordered a filter to do the DIY intake. Trans was rebuilt about 15K miles ago.

Is there anyway to tell if it has been programed? I assume I can pull PCM and tell if it has a chip?

What I'm looking for is driveability and better MPG with a shot of towing thrown in, getting about 15 MPG presently with minimal checking. As far a towing roughly 7 to 8000 lb max.

I would like an all in one unit with gauge screen with some custom tuning no smoke or race type tuning.

Thanks for looking.
Scott

If you're looking for an all in one gauge unit with aftermarket programming, then we offer the Edge CTS and Edge CS (re-branded as a Gryphon) and offer our own programming for them. We can do mild HP programs that are suited well to towing as well as daily driving programs that add 65-80 HP when you need it.

The programming is $25 per tune for a stock truck. We no longer offer alternate standard tunes unfortunately.

To check for a chip, simply pull the PCM out and inspect the rear of the PCM. There should either be a hole and a flat edge of a circuit board showing or there will be a black plastic cover about 1" x 2.75" . If there is an open hole with no chip protruding or there is a cover over the hole in the PCM, you don't have a chip.

Not to say that the truck hasn't been reflashed, but there is no chip in it. You CANNOT use a flash programmer such as the CTS/CS with a chip installed without ruining the PCM.....so make SURE that there isn't a chip connected to the PCM.

Here is a picture of the PCM case by the parking brake assembly. You will need a 7mm socket to pull the case bracket off and a 10mm socket to pull the PCM connector off.

Here are some instructions for you:

I went out to just look and make sure I could find everything and looking under the hood on the fire wall I found a cable that had EDGE Products on it braded line that goes to the drivers side exhaust manafold down pipe. I assume a gauge line with sending unit. I will pull PCM later to check.

It sounds like at some point it either had an Edge Juice module or an Evolution programmer installed.

Pull PCM black plastic cover on the back of it. So no chip. I wrote down all of the info off of the PCM. Ok I think I would be interested in a Gryphon CS. I want to be able to see the important temps and pressure on screen as well as increase driveability and MPG. My goal would is 12 to 14 MPG pulling my 5000 lb camper and 18 to 20 on the HWY. Will the Gryphon take care of the transmission as well?
I'm running 285/75/16 tires with D1 rear axel code 3.73 and the best I can tell from looking everything else seems stock. Also PCM code NVK2 if that helps?

Thank you very much for your help.
