2000 Monte Carlo SS proper fuel pressure?

Thanks for the responses on my SS issue. The fuel filter is a year old, and yes it does’nt have the pick-up it always had. On an upgrade you rarely had to push more on the accelerator to climb the hill. Now you have to push down a decent amount and it kicks down one gear and sounds real throaty through the air intake. It kind of feels like the difference between a car full of people and luggage (and maybe a small trailer) and just one person in the car (no trailer or luggage)! I have not had good luck with generic manuals. I usually break down and get the factory shop manuals but, I don’t want to spend the money right now. My Daughter is getting married this summer so I have to pinch pennies!
