my standard gti manual had a supposed 65bhp remap, had it on the rolling road 258bhp, 0-60 5.76 secs, not a bad £350 spent. 
where did you measure 0-60 and how did you do it (ESP off, etc etc..). Just curious
just got the time from a rolling road, my friend had his at the pod with the same map and manual, ran 14.18 @ 101mph. the company is celtic tuning, never hurd of them before but my friend recomended them and havnt had any problems, nearly 2000 miles since i had it done.
