is there anyway I can do live loging of boost, temps, ect with the xcal. didn't get a instruction manual or is it just for tuning.

U need to download live link and set up the pid selection then workout what it all means

I tried the gauges, whilst I got a few things to work, I couldn't get a boost reading.

Boost works but it is not in the usual form that people expect to see

Can't remember exactly now,

There was a few boost options like 'desired boost' etc.

I went off 'manifold absolute pressure' and subtracted the atmospheric pressure.

This correct for boost Mick? Would be nice to see a straight up boost reading in PSI though.

That's pretty much it, the ford ecu does not have an absolute psi reading to give out

Is that similar to how torque calculates boost?

torque? are you talking the torque app?

Yeah mick that's the one.

If it runs the same does that mean that the boost reading would be incorrect

If its reading a generic OBD2 pid, the number maybe correct if it's reading MAP, but the reading may be slow compared to what is actually happening at the time
