Nothing concerning there at all, some people only keep sporty cars for a year before moving on. Just don’t pay top money for it if you’re planning on doing more than about 5k miles a year, as otherwise you might as well buy a leggier example.
Looks like Sunset from that photo, but if it’s non-standard then it could literally be anything. Can prob get a pen from any NMD, but it could stand out more than the scuff. Any pics of the damage?
So Horsham did both the 418 and the 354 dyno runs, correct? Are Horsham saying there is def something wrong with it? What boost are you running? What size pulley?
What I’m getting at is this is lacking in details and Horsham know their stuff, so I’m surprised if they can’t fix it or give you a hint as to where to go next.
Without replacing the entire unit, you can’t. Tbh I don’t ever bother with in car nav either any more, get a good mount and use your phone: certainly the bigger models (Max, Plus sizes) are more than capable of giving you the info you need clearly.
Keep your foot buried past lockdown in normal mode and it’ll still shift at the redline. Also Sports Plus will still change gears automatically for you, only if you push the stick to the left and put it in manual mode will it not change up.
Get it to Center Gravity asap. Best money I ever spent on mine, absolutely transformed the car.
Same when I took the 6er there, too. Wizards, I tell you!
That was utterly painful to read, even as a Porsche fan. Also he gets quite a few bits wrong as well (there is no raised rev limit in Sport Mode, for example).
Used the place run by a mate near where I used to work, but honestly that was cos it was handy rather than anything else. An MOT is an MOT, go wherever is easiest.
