VF Clubsport in for a look into poor running at high RPM.
Once on the dyno, it was clear the spark was being blown out above 4,000 RPM. This wasn’t initially suspected, as the owner had recently replaced the plugs and leads.
Sure enough, the iridium plugs had no tips left!
In went a set of TR6 plugs, followed by a full dyno tune.
Now making a healthy 387hp, with the only change from factory being an OTR intake!
