Skok

Hello , i am using KSP 0.90. No mather what i try my pod does not get more than 400-500 degrees hot, even without a shield returning from the moon. I set the shockwave exponent to 1.06 for all 3 dificulties in custom.cfg but the results are almost the same. In version 0.25 KSP and DRC 6.2.1 all was working just as i wanted it to by only seting shocwave exponent to 1.03.So it would be nice if someone can give me some help with this. Thanks
