Well the fact that my truck is deleted, and I use my exhaust brake everytime i start my truck, also the CCV is no longer going to the turbo, that should expand its life a little more, but honestly to spend this money on the jit new valve springs retainers, locks, pushrods ,CP3 powerflow 750, I wouldnt hesitate to buy another VGT they have low mileage take offs on ebay so I'd grab one in a heart beat plus there cheaper.
