couple of questions about tuning

[stigi23]

i ran my XL today and after doing WOTs and after letting the throttle to neutral the idle is a little to high so the car rolls a little forward when in neutral, but after 5secs it stops rolling and back to standing still at idle.
Is HSN/LSN to lean/rich?

And also at full tank i got temperature just under 206 and so when i reach half tank (juster under the edge of the midtank) and pretty much towards till the tank is empty i have temperatures around 240. I guess its the htl kicking in. But should i tune the car when i'm at half tank? What temperatures can i safely pull without being to hard on the engine? I know i shouldnt tune exactly by temperature, but just to give me a clue what temperature i should look for.
I have run almost 1 Gallon through my truck now.

Stigi23 read this https://www.hpisavageforum.com/forums/showthread.php?t=12260. When I had problems I followed it and worked out for me. Your lean problems is coming from the tank design that is why most people go with the mid tank midification. Get the idle gap first then a good idle and go from there. What plug, fuel, and altitude you working with?

I'm from norway, but the name of the fuel is Rapicon 25% nitro and 11.5% oil, my altitude is 10m (33feet?) or something since i live by the sea. So i should set all the needles to factory settings then start tuning from there?

About the temps, if i have found a good tune, should i just ignore the temps?
Cause i had tuned it and ran good but under half tank i had temps around 300degrees, so i set it back to factory settings being afraid of hurting the engine running it at 300degrees.
