Feedback From Our Jeep Grand Cherokee Customers

Tony from Toowoon Bay, Australia with a Jeep Grand Cherokee MK4 3.0 CRD 240 said: I am very happy with the tuner on my WK11 Grand Cherokee CRD 3.0L. I was a bit sceptical at first but after towing my 2.6 ton caravan from Sydney to central QLD I am convinced. The ease with towing is so much easier on the car than standard, I don't have to put my foot down as much going up hill AND get better mileage. Thanks for the great service, help and advice!
Nigel from Horncastle with a Jeep Grand Cherokee MK4 3.0 CRD EcoDiesel 250 said: I have fitted the Chip Express to my 2017 Jeep Grand Cherokee 3.0L V6 EcoDiesel and it is more than meeting my expectations. Smooth delivery and an impressive increase in noticeable power, installed unchanged from factory settings.
Patrick form Calgary, Canada with a Jeep Grand Cherokee MK4 3.0 CRD 250 said: Super easy to install. We have left it on the default setting for now and do notice a significant increase in power and all the lag has disappeared when you step on the gas. We do see some improvement on fuel economy but it has also been -30 outside here!
