I'm in MI so not worried about elevation...As far as my driving, I do need to get the hang of it cause I get to much spinning of the wheels...Also, I don't have a bottle warmer, pressure gauge, or purge kit...Theres no way for me to know what the pressure is in the bottle...when i get all of these toys, my time should go down a little..And, I do notice a slight difference with the 55 shot..
