Are there any common complaints/problems having occured from using these boxes such as clutch slip, or flywheel, clutch, gearbox, diesel pump failure. Im assuming the diesel pump will be under more preassure?
I've looked and looked but all i can really see is good reviews. The figures for the price you pay are quite impressive so what is the downside/disadvantages? i.e whats likely to fail due to having these boxes fitted?
