Hi guys, I've got a 58 plate tuono with a pc5, to which I've had fitted a dyno jet quick shifter. All been set up on rolling road, dyno'd etc. All hunky dorey. Lately though.....Started acting up at silverstone, wouldnt go into 6th with the shifter, but fine with the clutch. Couple of weeks later at donnie, couldnt use the bloody thing in a gear! Took it back to supplier, back on dyno, much tapping of keyboards [changed the duration or some such bollocks] and it was fine. However, its started doing it going into 6th again, took it back, and ive been told that he might have to de program it for 6th. Now call me pissy, but i want the bloody thing to do all the gears not some! Does anyone know if there is an issue with q. shifters and 'prila gear boxes?? Any input much appreciated, Retep
