I work on Cummins diesel for a living and the vgt on the turbo must be programmed with Cummins software I would think if your turbo controller has a wire harness I would bet it needs to be programmed,buy the way I didn't know you could get the 2.8 in the TB,I'm thinking ColoradoHi new to this site need to know if replaced turbo and actuator need to be synced to ECM
ENGINE Diesel 2.8L
I'm really blind,I didn't see the flag next to the name,lm learning every dayThe 2.8 diesel is the same engine found in the Colorado. The South American/Asia version of the Trailblazer is different than the Korean made one that everybody here has. This version of the Trailblazer is based on the Colorado and is really a continuation of the Blazer while the one here in the US is totally different.
