thanks, my custom weights in at 167#, or about 100 over stock. I am in the process of cutting thru the 2" x 10" x 1/4" wall tubing to open up the air to the intercooler. Everything below the grill was closed off. The bottom 7"-8" of intercooler was blocked by the bumper or almost 50%. The window will be 6" x 26" and will save 15# off the bumper bringing it down to 150# or 80# more than stock. I am hoping to see a few more ponys with the cooler getting additional air. I peg the boost at 36, the truck runs great, but I just don't like the fact that the bottom half being completly covered. Maybe someday I will go back to oem and save the weight, but for now I will use what I have without spending some dollars, still make improvments.
