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.

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.

Suggestion
Unless you plan on trying a few different ones, it's probably best to just use the same one to get a 'before' and 'after' difference rather than a wholly accurate power reading.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi all, New to the forum and a couple of months in to owning my first Porsche. As much as I love it, I just didn't think it had the right sound so took it for a custom exhaust and remap yesterday. I am pretty surprised at the results as the 'before' graph shows it as having more power than as standard. Whilst I don't know if it has had any mods in the past, I assume not as I feel an exhaust/air filter would be the starting point. Unfortunately, I have very little knowledge of modifying etc and have thoroughly enjoyed reading through some discussions (and arguments!) on this forum regarding dyno's. Attached is the one that I have had. Does this look about right? Cheers for any thoughts to put the newbie's mind at rest.

POST 2Original post

Doesn't the standard cayman s have about 290 bhp? (According to Wikipedia) In which case it's about right now and had previously been a bit down on power. http://en.m.wikipedia.org/wiki/Porsche_Cayman

POST 3Original post

Depends on whether the standard power figures quoted by Porsche are at the wheels or flywheel. If it's at the wheels, then your reading of 285bhp looks a teeny bit under - 291bhp, or 295ps, were standard for a Cayman S, but if Porsche were quoting at the flywheel, then yes, your's looks a fair bit over at 328bhp. Different rolling roads can give fairly dramatically different readings though. Unless you plan on trying a few different ones, it's probably best to just use the same one to get a 'before' and 'after' difference rather than a wholly accurate power reading.

I believe the quoted manufacture figures are engine power, ie. at the flywheel.
