Hi, I think this has probably been asked before but i'm still none the wiser.i'm not entirely sure whether my 1.8t has been remapped or not. As i've never driven a standard 150 i haven't really got anything to compare it to.The only thing that i've driven close to it is a a3 2.0tdi 137hp and the golf seems alot faster but not sure if it's just the difference between petrol and diesel.Is there anyway of testing it out without using vag com cos it's proving pretty tricky to get hold of.It's an AUM 2001 Y (think Ko3s)I'm thinking same thing about my 1.8T buddy. Same year, engine code and turbo [3s] as yours. My car was previously owned by Lincolnshire Police. Am waiting on service history coming from force, to see if anything mentioned in there. Am going to get mine rr'd after oil and filter change, to see what I've got Obviously i'm probably just hoping here but would be good to know,Cheers,Jim
