Our newest tune offering focuses on improving the Grand Cherokee CRD fuel economy and part/full throttle performance.
The average fuel economy gain is roughly 3-5mpg depending on driving style and average speed. This is accomplished by optimizing the fuel combustion through changes in injection timing, fuel pressure, boost pressure, pilot injection events. EGR issues are eliminated and the smoke emissions are reduced substantially. For vehicles equipped with a DPF (particulate filter), the regeneration frequency is less and backpressure tends to be lower further improving the fuel economy. In normal driving the exhaust temps are 50-100 F lower than stock to improve engine and turbo life. The soot loading of the oil is also reduced.
Off the line performance is improved through improved combustion and an optimized turbo vane position. The 0-60 mph results show the GDE tune to be about 1 second faster than stock. This equates to about a 40hp gain at 4000rpm. Torque is increased from 1800-4000rpm linearly by about 40 ft*lb.
We have previously tuned the KJ CRD and have yet to have a dissatisfied customer.
The tune plus flash/scan tool is mormally priced at $750, but the first 10 forum members will receive a $250 credit. This is contingent on providing hand calculated fuel economy data for the stock WK and then supplying post tune FE data for peer review.
