I think it was about 1200 euros drom Germany, too much in my opinion, but it is the top zorst at the mo. They asked me twice that for a Titanium system. ...............................
I had the TOR tune initially. No problems with that dor the ZARD.
Then I bought a tuneboy and got supplied with a custom map which I loaded into the ECU. Still running that till I get the bike on a dyno.
