I’m trying to wrap my head around this tune. I love the idea of the high idle and the reduced turbo lag...especially at rolling stops and low speeds. But I don’t understand how it is possible to ask more from this engine than what it is stock, without compromising the longevity of the engine. This has to be putting more strain on it than what it is meant to take. Can you explain to me why that isn’t the case? Do you have data to prove you are not risking the longevity of the vehicle with this tune?

We have one customer that made it 371,000 miles on an ecodiesel ram with our tune. There are many stock engines that blow up with low miles,a tune cannot help with this field issue. However, the GDE tune reduces the soot in the oil by about 90%, this is directionally correct for improving bearing life and other rotating components. At full load the GDE tune still keeps turbo rotational speed within Garrett limits and that seems to be the weakest point on the stock hardware. Cylinder pressures are only 10% above OEM rated, this is still fine for an engine rated to 150,000 mile design life.

if you don't beat the hell out of the jeep or try and tune it for 700hp and 1200tq it will last a long time.
