I beat a modded type r pretty bad on a roll when I was bone stock. I raced from about 20mph-120. I puleed a head of him at first by about 2 cars then he inched back to close the gap, I had about a fender on him by 90 mph. Then neither of us were pulling ahead to 120 mph. He had intake, header-back exhaust, header, short shift, fuel pressure regulater, and fuel rail.
