Spoke with the owner of Maddad the other day and it sounds like these exhausts are just about ready for full production.

Got my car tuned yesterday (Open Source) by BrenTuning. Extremely happy with the results... below is an excerpt from a post the tuner made on another forum. It should help clear up a couple things concerning the #s.

Runs were done within 2 minutes of each other, on same strip of road. Only difference is we started the stock run sooner so the lines draw sooner. There are no low end losses.

Notes: stock map with a turboback, had a heavy flat spot between 3-4k rpms, pulled 2 degrees of timing globally - and peaked out at 16.25 pounds of boost. (map calls for 13.5-14 depending on rpm)

Tuned map at 20.5psi, 10.8 afr, and conservative advance. It made lots of power with the cam timing changes.

Large gains everywhere!

Stock vs. Tuned

Heres the dyno pulls from when I got the turboback installed:


Things to note is that the above is the difference from bone stock to 3" tirboback + cobb stage 2 map, gains of 20whp and 70wtq.
With Brens tune, the baseline was the stock tune + 3" turboback vs 3" turboback+brentune, gains of 45whp and 70wtq

While the final numbers are roughly the same, keeping in mind that there are variences in the way data was gathered, its still safe to say that the overall gains from bone stock to 3" turboback+brentune are actually more than 40hp/70tq.... in otherwords, nothing but a nice big on my face

Your graph says stock map and stock exhaust. Our delta was from exhaust + stock (higher delta then stock exhaust) to exhaust + tune.

With your exhaust I'd expect to pick up a good 25whp untuned, let alone the flow letting it peak 16.2 psi that the stock exhaust wouldn't do.

Perfect example of why dynos are good to see what gains were made and where they were made and not for trying to actually read peak #s
