The benefit (as I see it) for the AdBlue delete is you will not have to mess with it or the heater and pump failures that seem to be somewhat common. In my application (2012) it's a digital turn off of systems, also removes the DPF and SCR units. AdBlue injector stays in place, the new exhaust is a direct bolt on "(off road)" application. In respect to the environment, this system didn't meet specs in the first place and by increasing fuel mileage (what I'm told is a result) along with no more regens (read bumping raw fuel into the DPF and burning off) should be beneficial.
In respect to wear and tear, I'm thinking there will be additional wear on tires and brakes, engine longevity I can't say, really depends on how you drive and maintain it I'm thinking. Fuel economy is increased is what I'm told, hard to say now due to spirited driving. The missus seems to get a kick out of blowing around corners on two wheels and mashing by everyone in sight. Hopefully that will pass..... The transmission I'm told is a very robust unit and can handle the extra ponies and torque. Prior to I would typically see 8.2-8.6 litres per 100 Kms, the fun factor is too high at the moment looking forward to see what the future holds.
These vehicles are so refined (least compared to my 97 Ford powerstrokes), it's a challenge to judge rate of speed, due to superior handling and minimal road noise for a 5000lb vehicle. Was on a major divided highway going to Vancouver Friday for the tune and digital deletes, legal speed limit is 120 kph, I'm eating an apple driving one handed enjoying the autumn view looks down and I'm way North of 120.... like 150kph, rock solid. Coming home paying attention, not gonna say how fast it will go but I did over drive my new Hakkipellita 9 studded ice radials and I was not even near full throttle.... cheers.
