No offense intended but I'm seriously doubting that the HPS tubes give you 12 RWHP. I had the Cobb PMAF tubes (same thing) with K&N drop in filters and dyno'd

No offense intended but I'm seriously doubting that the HPS tubes give you 12 RWHP. I had the Cobb PMAF tubes (same thing) with K&N drop in filters and dyno'd 270whp before and 275whp after with 5 hp gain consistently from 4k up. Not sure why the HPS tubes would suddenly add 12 RWHP for just a bit smoother airflow. How were the outside temps/humidity/car temp/oil temp on the two seperate dyno days?
