If the PC allows the tuner to adjust the A/F and get the right mix thru out the rpm range, then it has done its job. All i said is the TB will do more . You can get a good a/f with the pc and all of the dynojet people are familiar with it. With Tb, You can't recall your tunes. So to make changes you have to save the tunes first,(in your Computor) recall a tune, make the changes to it as to a/f ratio,save, then re install in your bike. If more changes have to be done, the process has to be redone. Just save the tune on file before loading. Takes a little longer and you need to be good with a computor. I have a friend who excells with the Tuneboy and I can really appreciate it's ability.
The Pc will give you good af, but you can get the same with the TB plus all of the other. I used a PC on my Bonnie for a while and it did not adapt well to altitude. The TB eliminated that.
Just my preference. Adjusting AF is adjusting af, whether you do it with the PC or TB. The PC doesn't give better results, just easier for some to use. And, that's all it does.
