What are the signs of a turbo starting to fail
I have 21000 miles on my truck and have been tuned for 11000 of those. My truck was acting funny in the mountains on a ski trip. Seems to be acting normal now except I am running the 200 war hammer tune and it used to make close to 40lbs of boost now is only making 32 or 33. I am ok with this as it probably better for the turbo. I did put the cover back on the S&B intake that is the only change that I have made. Could the turbo be going out or would the cover make that much difference????
