Read evidence and context

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.

Discussions that performed work without a confirmed outcome: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

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.

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

POST 1Original post

So I've installed the ipd competition plenum and Tb kit on my 987.1. When you install you remove the rear (intake plenum) flapper and plug the vacuum line. So why do you leave the front flapper connected and operational?I understand that it has something to do with air pulses but does it really matter? It makes more sense to me to disconnect both... Could you operate with both disconnected and be left "wide open"? TIA

POST 2Original post

Call Scott at Softronics as he remaps the remaining resonance valve, Vario cam Plus, Ignition and fuel delivery maps to compliment the larger throttle body and Plenum. He also suggests a long tube header system to help remove the spent exhaust as efficiently as possible. His flash really improved my mid range torque a lot. I use Soul catless headers and a Milltek muffler.
