[director]Well I finally built one just to try it out and seems to perform well.I am running beta 4.4, will check numbers on the 4.11 progaming sw5 seems to be best mileage for me after this tank. For those who are worried about the turbo whistle it is no louder than the s&b I had in there maybe a tad quieter. Seems to flow good and egt's are down about 50 degrees 65 to 70 mph see about 500 to 550 degrees and that is in arizona 106 degree outside temps so for what it worth for those worried about not being a cold air intake. Checking to see if any mileage changes. But all in all impressed. definately worth doing ILO cost of a aftermarket intake.
