[928uk] Improve performance

[mark white]

Good morning Alex,
Thank you for your quick answer 😁
I have ordered the gearbox oil and hope to change over the weekend 
I think I might need new joints for the gear change I think John does them, hopefully I will hear from him later

I will look into performance after changing oil etc

Many thanks Mark from Eastbourne

Once these are installed, he or a few others can remap the fuelling and ignition maps using a Shark Tuner Mk2 and a laptop. Porsche did leave quite a lot on the table, particularly in the mid range. The cost of the chips and remap is very, very reasonable.
