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.

Suggestion
For early cars with mechanical throttle (DME5.2.2) you have to disconnect the battery for a few seonds.
Leading evidence: 'Disconnect battery' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Disconnect battery' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Just to add a brief +1 to Nick's comments about re-setting the adaption on the engine ECU.
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.

Worth doing? If so where is best place to get it done?
Vehicle still obviously fast but seems to have lost a little 'pace' [
] Is re mapping the best thing to do to increase power?
Thanks
Have you performed a forced adaptation?
With a cold engine, turn the ignition on but do not start the car or touch the throttle & leave on for 1 minute. Turn off & turn ignition on for at least 10 seconds & then start. Go for a decent length drive over a mix of roads.
Very dependant on how the car is driven. Short journeys on cold cats are a good way of killing them. My old C4 was still on its original ones when I sold it at 65K miles. My GT3 had melted its original ones by 45K miles but the replacements are still good and the car is on 90K miles now. It's probably done about 70 trackdays on the second set of cats.
Just to add a brief +1 to Nick's comments about re-setting the adaption on the engine ECU.
Mine (2004 996 C2 40th Anniversary) was re-set for the first time in my ownership during the 48,000 mile service & I wondered initially where the very significant additional performance had come from - the difference was really marked !
It was only after a lot of forum searching I realised what had happened & now make a regular habit of re-setting it.

For anyone who doesn't know how it is done, here are the instructions. These only apply to cars with electronic throttle. (DME7.2 and 7.8).
For early cars with mechanical throttle (DME5.2.2) you have to disconnect the battery for a few seonds. If you do this on an early car, make sure you have the radio code, and switch the ignition to position 1 before disconnecting, or the alarm siren will go off.
I'm gonna give this a go as I seem to have lost abit of oomph. Richard what DME do I have ? I know I should know this but you know what I'm like. Thx Roy
LOL! I DO know Roy. [
] Not that there is any reason you should know what DME you have.
You have 7.8. Just follow the instructions. Just need to wait for a day when it is 10C............
