So just over 2 weeks ago now I had my mk7.5 Golf GTI remapped with the APR Stage 1 tune. The car made a decent amount of power on the dyno and is all working as expected apart from the oil temps. On the whole I drive the car in a very 'sensible' manor and rarely stick my foot down.
Usually temps when driving the car pre tune were around the 105 celsius mark, but post tune I the most I have got to is 91c and that was from giving it the beans on a dual carriage way going from round about to round about. The average I see is around the 85 mark maybe a tad highly, which puts the car running 15-20 degrees cooler. From doing some digging on google it seems common for people to have 5-10 degrees cooler temps post tune but not what I am experiencing. I've spoken to APR and all they said was to put another temp gauge on the car and see what that says.. not very helpful.
I have the car booked in to have the issue checked over by the people who tuned it, but I'm wondering whether I am just being overly cautious and worrying unnecessarily.
Do I take it to be looked at, or is it just a benefit that the car is running cooler?
Should say that all other temps are normal, the only change it the oil.
