DTE Diesel Tuning - Plug N Drive

I purchased a tuning box from this company back in 2008 for my Audi A6 C5 2.5 tdi and cannot fault either the box or the company !The box took seconds to fit and significantly improved my power, torque and fuel return without question ! It has more than paid for itself over the years and miles.I'm currently looking to purchase another A6 C5 (final edition) and gave Andrew (chief bottle washer) a call to discuss options, again - I cannot fault the standard of advice or service from DTUK.Highly recommended !
