I think there is also a resistor modification?
ROM limit - I don't think the inline box modifies the RPM rev limit, only another CDI will do that such as an HRC or ignitech programmable one - take a photo and post your cdi? and how far up does it go? ie did you just get scared it was in the red or it actually went off the chart? from memory 14.5k is the limit, from a quick read it suggests that people generally read up to 15.5 standard ue to inaccuracies in the rev gauge, and the programmable box increase it to 16.5 indicated or so.
I did used to have an nc30 that went to a bloke in chch in 2011 or so which had an hrc cdi on it....kick myself now!
