Received the stg 3 from DNA, but will only be able to get around to test it next week. I will write a whole thing about it.

We will take Jon's XTZ back to stock to get a base run, then do a run with the stg 1 & 2 filter and then a last one for the stg 3 to show the difference.

Jon's bike currently runs a "stg 4" (self made DNA filter) for the right side of the airbox, so might show if there is more power to be had with more air.

Jon said that the stg 3 already made the Z feel more responsive and quicker, even though he already runs a side cover filter. Seems it will be a good one.

Hang in there, dyno runs to follow soon.
