Been a lurker for a while but recently registered.
Just purchased a 2004 996 Turbo from a dealership that knew very little about the car outside of the service records that came with it. Car has low miles.
It has a Fabspeed mufflerless exhaust(pretty loud but sounds good) The car, to me, pulls REALLY hard for just an exhaust. I've test driven a few of these now.
My question is, is there a way to identify if the car has a tune?

Thanks,
Rich

 

Is it a x50 or standard turbo? Check your boost pressure.
k16 do 0.6-0.7bar = 420HP
k24 do 0.8-0.9bar = 450 HP

Everything else means tune.

 

Non-X50
Thanks for the info. I wasnt sure how reliable the factory boost gauge is.

 

provided there are no leaks inhibiting boost? theyre as accurate as we've got lol. ghostofpain nailed it.
actual numbers from porsche at time of release were: 414 k16 & 444 hp x50/k24 car

 

if your .9 to 1 bar it has a tune
