wayne at chip wizards without a doubt.
look at the fastest clios around at the mo...unfortunately all mk1s as the mk2 boys all seem to use some inferior companies.
iv had kill power chips, iv used superchips, and only thing id recommend them for tbh is the bin.
wayne is an absolute genius, all he does is mapping now..and he still maps loads of race cars.
hes also a revo dealer now too.
hes done 3 williams' afaik, all 3 of varying states of tune, all 3 are pretty fukkin rapid for mods done. 2 of the 3 are in the top 3 or 4 williams' in the uk that i know of in terms of outright pace.
results speak for themselves.......and his results are excellent.the only 2 live recommended tuner in uk up to now. and thats a title that isnt easily earned.
