Interesting, they must have chose a bad one ?
I had a TDI box one many years back or something sounding like that when I had a golf 150bhp TDI when I fitted it their was an noticeable difference and use to slaughter my mates petrol Gti ! I think it’s best to find out who has one fitted ?
Thanks ste.

Are you sure he just didn't disappear in a cloud of smoke & back off due to over-fuelling.

Seriously, they do not work.

All they do (even the good ones) is over-fuel which is NOT a good idea if you want the engine to last.

If you want better performance get a PROPER remap.

Re-map sore point with a new motor as it can be detected and your warranty is void !
