its all well and good putting the 14s back on but there was a serious lack of grip hence me getting the bigger and wider tyres/ wheels. the overall size of the 16s compared to the size of the 14isnt much cuz of the low profiles, so that shouldn't make much difference . what tuning can i do to the diesel lump in it now?
you could uprated the turbo and also there are specialists out there now who do only diesel tuning, worth a Google.... dont now if the pump has got a rev limiter on it ?? most diesels have a throttle stop to limit the revs, you could tweak that!!
