I got lucky with a pretty hot disco from stock.Main reason for the tune was for accuracy.Could have sent it to other tuners for more power,but after talking to mike many times sent it out to him.triger mod and accuracy tune with a power adjuster.I dont have it set for full power,just shy of it.Shot a boat load of pellets over the crony to get it where I wanted it.(hint buy some crappy pellets to get your power curve ,then use some decent pellets to finalize your results).Now im useing Crhp's.going to try some RWS superdomes.Off the bench its shooting ragged hole groups and I know the gun can do better.I just have to teach myself the nuances of the new gun.
