Has anyone installed the BD or Banks intercoolers on their trucks? If so did you notice much of a difference in the performance? REason I ask is that they modified a stock one at work and improved the flow 30%. The stock one is pretty restrictive, but with some welding and porting I'm wondering if I'll get the same flow characteristics as the Banks or BD? I looked at the BD and aside from enlarging the tanks a little and the tube diameters it still looks as restrictive as the stock one. Haven't seen the Banks one.
