Safe Temperature Limit for Tuning

[svt2205]

Well I've had my Gryphon now for about 2 weeks and it's still in the box while I wait for warmer air to arrive here in NH. In the booklet it says not to tune at extreme temps, 20 to ???. I only noticed the cold side since that's what I'm dealing with.

What is a real safe temperature for me to wait for so I can try this new toy out? Our weather here in NH is cold and snowing right now. (sick of winter now....) with a week of cold temps during the day and single digits at night.

Bill, what do you recommend? I'm hoping I can install this before my custom tunes arrive. But if it's not safe (I'm an engineer so I believe in being conservative when necessary), I'm not going to install...

Time to go plow some snow...

Thanks
