CAT C7 ACERT Engine Info?

Hello all! Relatively new driver here and I just got hired on to be a rolloff driver. I am their first employee and they own about 30 dumpsters around Northern Colorado. They just bought a used 2005 Peterbilt 335 rolloff truck and it has a new CAT C7 ACERT in it, the truck is very nice and clean. Proud to drive it.

Now my questions begin with that CAT engine... I have only ever driven Freightliner DD15 engines in a tractor-trailer and with those you really only rev them out to 1700RPM, well that's were the power drops off and that is all the computer lets you have. It also builds boost as low as 900RPM and lugs really well. However, with this CAT it doesn't even build boost until the 1200-1300RPM mark and will keep going all the way till 2000RPM before thing start seeming a little rattly/over-revvy. It seems to run the best at the higher RPMs (1400 - 1800) otherwise its a real drag. So is it safe to rev the balls off this little kitty like that? Also remember if I blow an engine on the truck they just don't have another one to replace it, I'm out of a paycheck for a week while it gets a new engine.

Any kind of advice for this engine would be appreciated. Thanks
