VE Tables too high (at least double)

We've got a 2L non-turbo engine that we've just switched from traditional to modelled, 559cc@310kpa injectors.

The only problem is that the VE tables at idle are in the low 100's and it quickly max's out at 150 under load.

Injector size is set as per the manufacturers (Grams) documentation, engine size, all the fuel density values, etc all appear correct.

The only way we've found of getting the VE's down to a believable level is by halving the Injector Flow@Rated Pressure - what other variables are out there that can cause such a significant shift across the entire VE table? Fuel pressure at the regulator is reading correctly on both a analog gauge and it's sender too.

Can post/attach more detail after work, thought I'd get in early...

All the basic settings look like they are in the correct ballpark, can you give us a short log of it running.  Leave the injector flow set to the manufacturers value and give it whatever VE it needs to run.  

Where did that fuel pressure sensor calibration come from?, it doesnt look right since it is reading 66kpa with the engine off.  Most pressure sensors start at 0.5V for zero pressure and increase only to 4.5V and rated pressure.  Unlikely fuel press would make that much difference but still needs to be correct.

Your charge temp table looks fine as a starting point.  I would suggest turning off the IAT trim but that is not going to help your situation.
