I have a job 3 purchased new last June. When it was new I remember seeing the factory boost gauge go to 35-40 psi. The truck feels down on power now so I ran a few 0-70 runs to watch the boost. It hits 20 psi even at partial throttle but it struggles to hit 28-30 and will only do it in 1 gear. Dealer checked for codes and didnt pull any. They did the 08B07 reflash this morning and I didnt see any improvement.
What kind of boost should I expect? What factors could cause it to barely hit 30 now when it hit much higher 6-7 months ago? The truck is bone stock but did have the DPF replaced in October.
Thanks in advance!!
