Stage 1 XUD, overheating a bit?
Hi everybody,

I am having an issue with my XUD engined Cit Xsara. DHY engine, at 150k miles (245 k KM), lucas pump and KKK K03 turbo. 
I had done a stage 1 tune to it. It runs great, as much power as you can expect. About 180 degrees on the max fuel screw. The boost compensation screw fully in, then two turns out. The waste-gate screws adjusted to the end of the threaded bit on the K03. No smoke on boost (or a really light haze) that can only see in the headlights of cars behind me,  Rofl

Boosts to 19 psi on a really hard pull but to be honest I rarely push the car that hard. I do have mechanical sympathy and I do want to keep it reliable as at the moment is my only vehicle. 

Now I live in south eastern Europe as you might expect temps in the summer can be quite high. Few days ago while climbing a moderate but a fairly long hill in with the AC on the engine temp kept rising, it reached 100 *C and then 105 *C after which I parked on the side and allowed for the engine to cool down a bit. Both fans were on high, then when the engine cooled down a bit they switched to low speed. The rad is new, changed about a year ago, the same goes for the water pump. No low coolant levels, the car doesn't loose coolant what so ever. 

Now granted the AC was on, there were three people in the cars and I was maintaining a fairly high speed up the hill (80 to 85 kph) but still is this engine temp to be expected with a stage 1 tuned xud? 

I kind of worried of head gasket damage.
