Their baseline dyno is on that graph, 358 rwhp. Is that the baseline you were wanting, or did you want the baseline with headers/bolt-ons installed before the cam swaps? I was just amazed that they were hitting over 500 rwhp with a cam and some bolt ons.
Maybe these threads will give you the information you need. Two different cars, but it lets you know the power picked up by individual mods with a tune. The second link might be the car the previous poster mentioned. It made 433 rwhp after a tune with the headers.
