Ya definatelty pull that sucker off, if you need a hand let me know,the last 2 torque yield bolts on the blower are a nightmare as they are right under the firewall. As long as you're careful, the gaskets and bolts can be re-used. I wouldn't mind making a trip out there. I am assuming you're storing it for the winter? If so, best time to pull it.
The temps for your pulls were good, hot air KILLS our trucks, I don't even like driving mine when it's hot oustide cuz it's so doggish that it's disappointing.
Who's going to tune the truck? Find a handheld?
It's all about the boost!
