Intercooler position

Sounds like it\'s overcooling. Check the thermostat - unless you have a cool running thermostat (Which i don\'t see the point of as it means the engine is running below optimal temperature)

At the moment, driving to and from work I dont see temps higher than 79 if I stay off boost! - OE Rad & Thermostat.

I thought the thermostat started opening at something like 65/68?

no, thermostat starts opening at 80/81 degrees c. I\'d check your thermostat if i were you. I knew mine was sticking open once, as i had an aftermarket coolant temp sensor and gauge, the sensor was plumbed into the rad line. I could see this gauge starting to show temps as soon as the engine was started, which proved that the thermostat was sticking open. I now seeit only registering a temperature when the Apexi shows 80 degrees C, so i also know it is operating exactly as it should. And even in this whether i never see under that temp. However, i regularly see temps of only just above 80 in this weather.

I suppose your thermostat could just be opening a tad early.

Ah thats true.  

My journey to work is not all that long and once it gets to 79 on the commander then it stays there till I boot it - guess its just a tad early as you say!

It\'s a bit funny really I see lower temps now, but remember the ambient temps are lower and also I am off boost as I\'m running the engine in so revs are under 4k. So not a proper test as such but it\'s lower than I remember it being when I was pootling about or in traffic with the stock setup. Thermostat is a new oem one, will get a better idea once I have some more miles under my belt and the rev limit is raised/car is mapped.
