not 150 but in the high 80s and low 90s at the moment, itll start to heat up later this month and into august though. Ive heard of other people just starting on dino n switching to veg then ending on dino and it seems to work fine. theres a video on DISCOVERY.COM where they do the same thing and it seems to work fine. i dont drive my truck enough to spend 680 bucks, just wanted to see if it would work!
