I installed Bob's predone guage kit two days ago and I also bought the AIH delete plug with the boost kit and code eliminator.
Here are my thoughts: Bob's directions are great. Sometimes on the pictures I had to turn them to be sure the picture's orientation and my own were the same. As for the code eliminator, there was no mention in the instructions of what to do to the black wire coming from the heater. I just followed the directions and took off the wire and I have not recieved a code yet so I hope I did it correctly.
I did not ask or call but I think you can shorten the boost tube and the wire for the transmission temperature BUT NOT the wires to the pyro. I would be carefull not to run any of the wires near anything that gets hot. I bought looming and it worked great. I would loom it before installation becuase I did it after and it took a while longer and was difficult to get into some small spaces.
The pyro instructions say to drill a 1/4" hole. I did and the pyro did not fit. I was careful, slow and methodical so that I did not get any large metal pieces in the exhuast when I used the 1/4" bit to make the hole slightly larger at the edges.
To save time before you get the guages or before you install (if you won't be driving your truck after) you could go ahead a take off the factory A-frame and remove the heater and install the code eliminator if you bought it. To do this you'll have to remove the plastic Powerstroke cover that sits over the fuel filter access. You could also drill a 1/4" hole into your exhaust pipe about 2" after the transition from the manifold (be sure you know where this is before drilling or it might be better to wait for the picture (but you may know and it would save some time on the install).
I hope this helps. In all, it took me about 3-4 hours. I go very slow and am always having to look for tools, stuff, etc. You may not have the same problems. Good Luck! If you have any other questions, I can help as I am sure many others could as well.
