Player can get this tuned motorbike if he have high enough tech ability when will met Jackie waiting near food factory in Act1. There is special reply where V say something about poor exhaust due sound of it. In Jackie's garage will be then tuned arch in Act2 (Gig Heroes). There should be different exhaust, but I didn't checked that detail ... I will attach screenshot.Anyone know anything about a special version of Jakies Arch called "Tuned" Jakies Arch? I got it via a glitch while trying to remove all the dam vehicle markers from my map. And I rode it around but I do not feel that it is any better than the normal one.
