Nope.
Not required, I am changing just intake manifolds, plenum and throttlebody, people change plenums and throttlebodies all the time with no issues, if I have an issue I can speak to Softronic for a tune.
I can do the install myself, its not complicated!
Intake manifolds 4hr-6hr job, change spark plugs at same time too.
Plenum - 30 minutes
Throttlebody - 30 minutes
A Porsche veteran would do the above in sub 4hrs quite easily.

If you did the work yourself, then maybe it makes sense, at least the parts are proven... keep us posted on the progress and results. PLEASE do a Before/After Dyno, otherwise, there's no way to know if it made any difference.

You 100% need ECU program, ECU will learn within a set of boundaries, it's not magic. X51 has a totally different Torque curve, and needs a new program to adopt to the increased airflow, etc.

The ECU re-programme is not needed to run though, I could nicely ask Porsche for the programme but my car won't be full X51 as its still missing the revised cylinder heads etc.
The stock ECU tune will adapt a little so all runs well, just might not get the full advantage unless one gets the X51 map or uses softronic.
So now I just want to add the intake manifolds, X51 plenum, X51 throttlebody, thats it just along with all the accessories required which is gaskets, tank vent hose etc.

Hello, I know is an old post, but I find myself in need of replacing the intake distributor pipe (997.110.416.40) on my 2007 C2S. I would rather eat glass than visit my local Porsche dealership ever again (long story). Can this be purchased online somehow?

I had an '07 C4s X51 (still my user name). Before that I had an '06 C4s stock. Other than PSE, I really couldn't tell the difference! 26HP sounds significant but in reality it is about 7% more which really isn't all that noticeable. And the factory X51 engine is so much more than some bolt on add ons. If you want an X51 engine, I recommend you buy a car already optioned from the factory. The dealership here in Louisville KY has a Seal Gray on full leather sport seats in black '06 C4s coupe w 42k miles for sale! Don't get me wrong, I like to mod & personalize my cars too, but something's make sense and some things make no cents
