It has been awhile since I have had to come and say hi to all my Powerstrockeian's, hope all is well and Happy and Safe holidays. My truck is acting like it has Covid, working hard up hills and just not having the power it used to. I keep it well maintained meaning oil changed every 5,000 along with fuel filters and coolant filter. I have been noticing that the boost isn't what it used to be, when at WOT I am only seeing max 20 psi. There is now 230,000 miles on her, aside from the low boost problem how long do the injectors go before needing replaced? Any suggestions would be greatly appreciated.
