Your truck has been robbed of low end torque ... which is why you are not seeing the fuel mileage you should!
To meet today's emission standards truck manufacturers are being forced to de-tune the low-end power !
My company has spent the past 10 years working with diesel truck owners just like you and we understand your frustration with this poor fuel mileage situation.
You are driving a nearly $60K diesel and like other Duramax owners you are pissed-off with its current fuel mileage... and you are searching for an 'affordable' and 'easy' solution to increase it's economy.
Even though fuel prices have come down they are still outrageous and affect our wallets.
If you make a living with your truck every fill-up cuts into your bottom line. In a struggling economy high fuel prices and low fuel mileage makes life tougher.
