Hey there buddy. Ive got a 07 CRD with a Cross country intercooler. Cant really compare it to a std intercooler because it was fitted when I bought the truck, but the guy I bought it from did say when he fitted it it knocked at least 50 of the top of the egt. Also once when I had an intermittent problem with the truck and called a mobile mechanic (this guys was into 4wds himself) we went out for a drive with his little gismo attached to the ecu, we were only doing about 45 - 50kmh at the time but he turned to me and said " that larger intercooler of yours is really working, the gauges are reading your intercooler temp at only 20 degrees C". that had me convinced it was a good thing at the time. Hope that helps you some. Dan
