The misses had 1.4 tsi rocco mapped at inters and had no trouble since, but after discussing with revo her ecu doesn't have variable settings like ours, it's just 3 settings. 95 Ron, 98 Ron and 101 race fuel.
So easy to decide a setting depending on fuel. Whereas the TFSi need boost, timing and fuelling setting so not to easy to distinguish without logging I suppose, just like to save money but maybe it's not worth it, may as well pay the extra 100 and no it's right.
My local revo dealer is Clive Attowwe in Norwich, Norfolk.
Speaking to revo hq at inters last year and they all know clive and speak very highly of him so may have to bite the bullet!
