Originally I was running the Triumph tune for tors , I had the Ramair and pcv with a generic tune in the pcv . The bike was running very lean with a lot of decel popping . I was not proficient with tune ecu so I had the bike dynod , The tuner wrote a custom map for the pcv and changed settings in the ecu , ie opened the secondarys , raised the rev limit , removed the restrictions and lowered the fan operating temperature . This transformed the bike with no decel popping . In the tuners own admission , he tuned the bike for optimum running through the entire rev range as opposed to optimum power which I was very happy with . On fitting the Dps , I had assumed I would need a retune and have since acquired tune ecu . That said , the bike ran lovely with the DPs fitted with only the very occasional pop which I don't mind . On giving the bike it's 10000 mile service recently and changing out the plugs , I notice that their colour is nigh on perfect and certainly not lean overall , so for now I am a happy bunny ! I have learned a lot from this site and if the tune drops out or needs tweaking I shall now be appealing to
@HansO and making adjustments via tune ecu and possibly even doing away with the pcv . I certainly believe that handso is the man with a tune for every application and one helluva lot cheaper than dyno time !
