These guys are the best we ordered a turbo from them for a Duramax LML, and it came with the center section for an LBZ they found a cooling line for us to use the turbo made a credit towards the labor. Then the turbo had another problem, it was leaking exhaust out of the middle of the housing. They arranged for another turbo to be sent overnight at their expense unlike another company who made us take the turbo off and send it back to them before doing anything making our customer have to wait over 2 weeks. Can't say enough good things about Mike and his crew at TurboTime
