got the retune done on our au i6 today and the results are a tad different to what i expected
with the original head it made
159.2 rwk @ 5400 and 321 nm @3800
now after fitting the new head
156.7 rwk @ 4900 and 348 nm @3200
can't wait to get a bigger cam
c and j did the tune both times and are great guys to deal with .

going buy the seat of your pance feel, it feels a lot stronger than before . definatly feels quicker.can't wait to get it back out to willow bank for a run.
