Hi this is my first post

i have had my FD for 6 months now, love it to bits,
when i brought it, it has a lot wrong with it but over the last few months i have spent a fair bit of cash on it to clean and tidy everything up, only have to put a nice new ECU (LINK) into it now

But anyway back to the point, my Rev counter only sometimes might i add, moves around i'll be driving at 50KMPH and the rev counter will go from 2000RPM up to 3000RPM or even 4000RPM.

any ideas?
