New data log
I managed to sort a few issues I had with my car and it seems to be running better so I quickly popped out for a drive and it was quite busy but I managed to have a little blast and took this log.
I will do some more later but wondered if you could take a look please

Nick, for your second pull, your IATs reach about 46C, which is reasonable. However, without doing a sustained load with several VMax pulls, it is hard to say how easily it gets soaked. For the purposes of that specific run, your ICs seem to be doing their job well. However, it's hard to say what the thermal efficiency is without measuring the temperature before and after the IC...Durametric won't log that info, you'd have to put a probe into the pipes before and after the IC to get that data.

In log 2, initially, it looks like the ECU is pulling a timing at peak torque around 5K RPM. It maintains reasonable Lambdas and a boost of about 1.2 at this point. As you reach 230 km/h, at peak torque, you start to run rich.
I'm not sure why, as your IATs seem okay, unless you are just letting off the gas at that point.

Disregard. Looks like those are in km/hr.
Yeah seems to go pretty rich up top. IATs are "ok" for 1.2-1.3 bar up to those speeds -seems like they were a touch better on some of your older logs though. Have you run a leak check lately?

Dave, is the blue curve a graph of engine load from the Nick's data above? Don't know if I am missing something (new to this of course) but it seems Nick's data shows max engine load is at around 4400 rpm , here it is at 3000, making the torque plateau a lot wider than it should be?
