112 is waaaaay too low. It needs to be in the 200-205 range to properly break it in. You can do just as much damage to the mill this way as you can running it too hot. I heat cycle break in all my mills and have always had great luck with them. Hell, the original .15 fe from my RS4 3 will still fire up in under 3 pulls more than 5 years later, and who knows how much fuel. My S-25 in my Savage SS would wheelie on command with 15-49 gearing all day, it's now over 3 years old and numerous gallons and was still strong as hell until the pull start broke, so I just threw an Ofna Picco .26 in it. The Ofna .26 I broke in for a friend will flip the truck on it's lid real quick and never runs hot. My WS7II is an animal and it's only on about it's tenth tank and stays around 230-240 after wide open runs. But I don't have much fuel run through it yet so I'll have to see how that one lasts. But no matter what you need to get the temps up, AND vary the rpms, which idling through a tank does not accomplish, to properly break it in. NOOB!
