Scan gauge question
Just installed Scangauge & set up coolant & oil temps. Decided to add 2 more gauges & used Boost & HP. When running truck with heavy load (26000) I noticed that the boost gauge would go negative & the HP gauge would drop considerably. In a little time it would go back normal. I used the values for 6.0 & Ford specific tables.
Does anyone have an idea what is going on?

Do you mean under Hard Acceleration Boost would go negative??
check this thread out Boost may take a little playing with to dial in

Boost
TXD-07E0221440
RXF-046285140640
RXD-3010
MTH-001D0050XXXX
MAP is a standard gauge - but this XGauge is actually better than the standard one. It has a larger range which was needed because the standard gauge tops out around 37 psi absolute (about 22 lbs of boost), which diesels have no problem doing. This one should read well beyond 22lbs of boost.
With a little tweaking you can adjust this to read boost as you said.
To do this, just plug in the MAP code - get a reading from it with the key in the on position but the engine off, then based on the reading changed the last 4 digits of the MTH to whatever corresponds to your reading on this table
12.7 FF81
12.8 FF80
12.9 FF7F
13.0 FF7E
13.1 FF7D
13.2 FF7C
13.3 FF7B
13.4 FF7A
13.5 FF79
13.6 FF78
13.7 FF77
13.8 FF76
13.9 FF75
14.0 -- FF74
14.1 -- FF73
14.2 -- FF72
14.3 -- FF71
14.4 -- FF70
14.5 -- FF6F
14.6 -- FF6E
14.7 -- FF6D
14.8 -- FF6C
14.9 -- FF6B
15.0 -- FF6A
So, for example if you got a reading of 14.5 PSI with key on engine off you'd change the MTH to 01220320FF6F and the reading should read 0.0 with key on engine off and would then show how many lbs of boost you were at when the vehicle is running.

Also, check which version you have. If it is 6.0, it will read pending codes.
Go to their website and read up.

I was testing 2 boost gauges just the other day and one didn't work. Checked and well, I missed a number.
