I am using just the Power Puck. My truck tows my 30' just fine, but I always wanted that little extra. I went with the Puck b/c it was 160 shipped and heard some decent things about it. Power is smooth and the increase is easily felt even on the 60hp setting. I can get the egt's up to 14 if I keep the boost up and foot in it. I did not have my egt gauge installed before it so I would bet money stock was getting up there also. For the price and ease of install and power increase I really think it cannot be beat.
