@Cobb, I'm not sure if it's 2% but I do have to use a fair amount of throttle to maintain 55-60mph going up it.
I'm not sure what temps my fans kick on, but I can tell when it does when I'm climbing the Cajon pass every night (6% grade) all the lights on my dash dim for a little bit and when the coolant temp drops all my lights un-dim(?) so I'm assuming that's my rad fans.
Thanks for all the help guys, I'll remove all except the lower rad block and see if my temps drop, if not I'll remove it completely. It could also be due to the fact the rad system hasn't been changed in at least 6 years, could be as much as 10 I honestly don't know for sure.
