early 99 losing boost - any ideas?
I have a boost gauge in the truck - I have noticed that it reads lower then it use to when I first got the truck. At 1200 rpm it is now reading 1lb of boost instead of what I think I remember it use to read 3 to 5 lbs. This is not on the chip. Truck also takes a lot longer to kick in and move for passing then it use to.
So my question is what do I look at - Turbo broken fins, inner cooler, system tubing leaks or all the above?
Truck / motor now has 188,000 miles on it. I have also been wondering when injector service/replacement should be done?
Thanks for your help. Daryl
