Have any of you seen this? Its a 03 lb7 IHI turbo with a EGR system!! Is there a special tune that needs to be loaded into it to make it run better? Could GM have loaded a regular lb7 tune into it and thats why its not running worth a shit?
Since he picked it up from the dealer after they worked on it the truck has like 150hp. The truck ran fine before it went to the shop. Now it has no power.
