Technical Anybody see anything wrong + any suggestions???

The cranking rail pressure is significant in relation to the starting problem
Looking at your first readings the intake air temp should not be -40 degrees c

You could try unplugging the MAF sensor and seeing if performance improves-you will get a check engine light

The rail pressure is significant in relation to the starting problem etc which is why we have been asking.

Yep gotcha. Could that also explain the rough running when warm? If so are we talking high pressure pump?

Still pulls fine, not really down on power and getting 49mpg so can’t see MAF being an issue
