Normal behaviour for stock radiator when tuned

[AKKO]

UPDATE: My fans are deffinately on but only at low speed with temps around ~100 degress.

This fits with expected operation, and good to know there's some improvement to be had if desired as follows:
- bumper vents & under tray to force more air flow through radiator
- fan controller / switch to induce full fan speed
- lower temp thermostat to induce improved cooling of higher volume radiator.

Note as mentioned some of the above wouldn't be recommended with the OEM setup as could promote excessive fuel consumption as previously indicated.

For an update on this thread, I found a minor leak a while ago in one of the turbo line hoses off the thermostat housing. Tightened and have not seen temperatures climb since, although I haven't gone for a mountain run for a year.
