Should I add an IPD Plenum?
I have a C2S 2009 with PDK, Tubi exhaust(center muffler delete), softronic ecu tune, fabspeed CAI.
I did these about 3 months apart from each other in that order. I felt the CAI the most, maybe because it was the last mod and it all came together.
Is it worth it to get a IPD plenum in addition? And why?

I did do a search and I am not sure why you think the data was negative. Could you please be specific about what you think is not worth it per the data. Thanks

Dyno and my butt did not lie
I am very happy with the combination of the center muffler delete with the fabspeed CAI; I think with respect to physics it makes sense to improve laminar flow into the combustion chambers; if you look at the GTS with the x51 powerpack - the plenum from porsche is different (aluminum) instead of plastic on the 997.2 S. This also leads to less thermal mass issues.
I have noticed a massive kick in the pants with all of the mods. The dyno didn't lie. My experience with the GIAC flash (hand held able to switch between factory and pump program) was both I felt it (before the dyno) and proved it with the dyno 12HP. The car dyno'd out at 375 WHP; I posted the results awhile back.
For reference my car is a '10 C2S 6 speed.

i say save your money...evo intake, giac flash and suncoast/evo headers added ZERO to my 997.1 S
and yes - i did before and after dyno same day and different days with multiple runs....

I read thru most of it and regardless of the real dyno many guys say they feel an impressive difference with their butt dyno. So even though the results were less then what was expected the feedback is actually very positive by most guys who have done this mod. I am sure my cai would not show any gains on a dyno butt I sure did feel it and the net result was a big smile on my face.

Look into replacing the header/catalytic converter components. OEM parts are restrictive & somewhat crude. As aftermarket catalytics are less restrictive, the exhaust will be louder. Don't expect large power or torque improvements with any normally aspirated motor.
