I think it will move this truck pretty good and get decent fuel mileage as I plan on driving it a lot when done. I did ask about accuracy and they said they compared it with another dyno in there area and it was close and as you say these ls motors can make some power with the right components. Also for the price it was worth it. For the engine, rebuilt 4L80E, ECM programmed for my truck and stand alone harness tagged and instruction on hookup for $4500 delivered I don't know how you could go wrong. Steve
