Went to local seat dealership to get my new key coded and every since I got the car back it feels slower, also not as much black smoke and as loud or long the whooshing from my turbo (its a tdi fr150) was just wondering if they could of wiped my remap off? Anyway to check? Also if this is the case how do I get the to fork out and pay for a new map?
 
Coding a key doesnt remove the remap, i've had a new key for a mapped tdi from skoda

But they may have flashed the car with the latest software. But i doubt that
