Longer crank times

My truck seems to take longer to start than usual when hot. I plugged in auto enginuity and it had a code for low boost and ep. But this happened when I split the 45 Degree cac hose right off the compressor. The icp pressure is 850 lbs when running. I'll see what it reads next time it does it. I got the factory workshop manual cause I was thinkin HP oil leak somewhere. But now I'm thinkin batteries. It turns over slower when it takes awhile to fire (about 3-5 seconds) Before this issue it would fire right away. I just had it at the dealer for tranny and coolant service and to have the batteries checked. Wonder if they load tested them and that took out the batteries. They're motorcraft and are 3 years old. I also live in AZ and it's been 105-110 here.

Oh yeah.......engine is all stock (no tuner) except air intake and exhaust.
Any help would be much appreciated!!!!

Batteries are the NUMBER ONE cause of hard starting. Many have thought otherwise, only to realize the batteries are bad or going south. 3 Years is about right and they do die fast!!!

I data logged my runnin around today........Battery voltage dropped to 8.3 volts when I started it. Seems pretty low to me.It still started pretty quick though. Takin it back to the dealer monday, it's free replacement for 36 months and they're at 37 months.

Although I do agree that most batteries die fast (a couple years), sometimes they will last longer. My Dad has a '99 SD that had both the original Motorcraft batteries in it until March of this year; never had a problem until one finally started to not hold its charge very well. He only replaced one at that time, and has been fine so far; but we'll see when colder weather hits. My on battery lifespan.
