Anytime! The Dynojet PCV with the A/T unit is a great piece of technology. But tuning the thing is a learning curve for all of us. Myself, I'm having a blast screwing around with my MAPS and seeing how the changes I make turn out on the bike. One thing I can say so far is the PCV with an A/T unit makes a great tuning device for the guy who likes to make changes to their engine. Sure if you want an exact MAP for your bike you need to go on the Dyno. But for the average rider, this is a great unit!!
