Back in the day I had two T4's remapped; once at chipwizards and once at Pendle. Both took several hours, rolling road, lots of tinkering. £350 odd quid for half a day seemed back then like quite a lot of money but it was worth it. Now I read Revo is the place to go and found a localish place to go so I ask how long and get told half hour! £400 for half an hour! So that's a plug in and generic map.. suddenly I'm less keen. What's changed? Why can they just plug in stick a generic map on and charge £400, why doesn't it need a rolling road and carefully adjusted to suit? Do Pendle still do it on the rolling road or has that changed too?
