Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Thanks @olv - Great video link - Seems to answer a lot of the questions about changes to inlet and exhaust built leaves the questions about ECU changes open and the question about ECU changes made together with inlet and exhaust changes.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • PistonHeads: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

Hi Folks Forums forums everywhere and not a clear answer in sight. Only interested in measured engine power increases experienced by other owners of the 996.1 3.4 after tweaking, tuning (chipping or ECU program) or adding performance parts like - IPD Plenum, 82mm TB, Exhaust manifolds, cat delete. OK - I’ll start 2001 996 3.4 e-GAS - bog standard in every way. Tested power and torque via multiple runs on a Dyno - Tried changing my standard Porsche paper Airfilter element for K&N version - Measurable reduction in HP and Torque - Yes I have the charts to prove. Went back to the standard Porsche Paper Filter elements - Power and Torque restored. All tests on same rolling road at roughly the same outdoor temperature- so like for like,. Who wants to go next - Real life experienced and honesty here please not interested in anything without measured results. (The K&N filter above sounded faster but wasn’t!).

https://www.youtube.com/watch?v=mc9c07qCuKY That video does some good comparisons of different intake options. The 3.6 M96 in the 997 is largely the same as the 996 3.4 and 3.6 so is relevant. They did a similar video on exhausts too.

POST 3Original post

daft mod this on 996 and 997. Ruins them IMO IPD, 82mm throttle body etc kills torque and power

POST 4 / ORIGINAL POSTEROriginal post

Thanks @olv - Great video link - Seems to answer a lot of the questions about changes to inlet and exhaust built leaves the questions about ECU changes open and the question about ECU changes made together with inlet and exhaust changes. Anyone want to chime in on these topics?

POST 5Original post

Desert Dragon said: daft mod this on 996 and 997. Ruins them IMO IPD, 82mm throttle body etc kills torque and power I was just going to write something along the same lines. Wayne at Chip Wizards hates them. One for the definitive “Flush money down the toilet” list.
